O-scores version of the Björn Kjellström Cup

2010-07-09T12:09:00.000-07:00

Following discussion at Attackpoint, here is the O-scores evaluation of the CAN/USA team efforts

(EXCEL Source file is here) and here are overall Performance list and O-speed table

Following table of runners was used, top 3 O-scores from each country, same people as in discussion above.

Runner	Class	Club	LONG	MIDDLE	Short
Alison Crocker	F	USA	114.4	109.4
Angelica Riley	F	USA	90.8
Carol Ross	F	CAN	93.9	106.9	97.3
Ekaterina Orekhova	F	USA		96.5	90.7
Louise Oram	F	CAN	115.4	119.1	101.6
Marie-Cat Bruno	F	CAN	87.4	92.4
Nicki Rehn	F	CAN			89.8
Samantha Saeger	F	USA	112.9		107.8
Sandra Zurcher	F	USA		112.1	104
Boris Granovskiy	M	USA	128.1	127.4	120.4
Brian May	M	CAN			118.1
Eric Bone	M	USA	131.3	136.1	121.5
Mike Smith	M	CAN	141.7	143.3	125.5
Nick Duca	M	CAN	126.5	134.2
Patrick Goeres	M	CAN	140.3	133	131.9
Ross Smith	M	USA	132.3	145.4	118.6

Following table of results was compiled (plain sum of all related scores)

	Club	Class
	CAN		CAN Total	USA		USA Total
Values	F	M		F	M
LONG	296.7	408.5	705.2	318.1	391.7	709.8
MIDDLE	318.4	410.5	728.9	318	408.9	726.9
Short	288.7	375.5	664.2	302.5	360.5	663
			2098.3			2099.7

Resulting sum of scores for each country is amazingly close (2098.3 and 2099.7)

Accuracy of the score calculation doesn't allow to call winner on the margin of 1.4 points.

What is clear is that USA ladies and Canadian men are significantly better than their corresponding rivals

Billygoat results 1979-2010

2010-06-01T20:57:00.001-07:00

Here is even more questionable analysis:

thanks to times published in the convenient format at billygoat.org I made O-speed compilation of all Billygoats 1979-2010

Notice that average score for all events 1979-1999 is 50, because Billygoat is the only event available for these years and average runners by definition must have score 50.

Power at the view above is calculated using current power of the runner ( calculated within last rolling year), so evaluations do not matter much. If one goes to the event view, all powers for early years will be identical to the scores, as Billygoat currently the only event for each year before 1999.

O-Scores calculation methodology

2010-04-21T10:55:00.000-07:00

External links:

http://www.attackpoint.org/discussionthread.jsp/message_149323 discussion about GV calculation

Original Methology post at Geocities is no longer available and I do not know where it was moved.

http://www.geocities.com/nikdangerdvm/03methods.html - original write-up of the GV algorithm calculations.

Methodology was called by many people as cumbersome and I will try to explain here in my words.

I will quote the Methodology where applicable and explain practical application details.

Originally Adapted for USOF from Wyatt Riley's BAOC ranking rules, 1999.

One more time adapted by S. Krechetov

Definitions:

There are four items here and they all depend on each other. Must be consumed as a whole dish. Don’t get disappointed until done reading.

Runner Local Power (RLP) = Race Gnarliness Value (GV) divided by Runners Time (RT)

RLPⁱ_r = GV_r /RTⁱ_r; where r is running over all races (1..N_R) and i is running over all runners (1.. N^I)

Example: GV is 5000, your time was 1:40:00 or 100 minutes. Your RLP for that race is 5000/100 = 50.

Runner Global Power (RGP) = plain average of Runner Local Power (RLP) over all races

RGPⁱ = 1/N_R*sum_r(RLPⁱ_r)

Runners Race Difficulty (RRD) = Runner Global Power (RGP) multiplied by Runners Time (RT)

RRDⁱ_r = RGPⁱ*RT_r;

Example: If your RGP = 80, and your RT = 60 minutes, your RRD would be 80*60=4800

Race Gnarliness Value (GV) = harmonic average (reciprocal of average of reciprocal values ) of Runners Race Difficulties (RRD) for all runners in current race

1/GV_r = 1/ N^I *sum_i(1/ RRDⁱ_r);

Example:

· John has RGP = 100 and runs RACE in 30 min. (RRD = 100 * 30 = 3000)

· Mary has RGP = 60 and runs RACE in 100 min. (RRD = 60 * 100 = 6000)

· 1/ GV = ½ (1/(100*30) + 1/(60*100)) = 1/4000

Then

· GV = 4000

Some observations:

If you are on average twice as fast as somebody, you should end up with about twice their score.

Practical Implementation details.

Input data for the algorithm are three columns: Person, Race and Time. No other information is needed
All valid finishes of the season are used. Valid finishes are times (not OT, DNF, MSP, etc...).
Algorithm is recursive over items 1-4. Must be stopped after next iteration changes results by negligible amount.
Initial conditions are Runner Local Power (RLP) which can be set to any positive nonzero number
Algorithm converges to the same point independently on initial conditions. For simplicity all runners can be given RLP = 100 at first step
Algorithm is linear relative to initial conditions. Meaning that if all initial RLP are increased by factor F, the resulting GV, and RGP will be increased by the same factor.
The only nontrivial output of the algorithm is set of GV, which is one number per race. The rest of the results can be immediately derived from GV and Runners Times (RT)
At the last step, all RGP RGP, GV are normalized so that 1/ N^I*sum_i(RGPⁱ) = 50 and the rest of the quantities are changed proportionally.

Additional Notes

Final RLPⁱ_ris score of the runner for this race. Using scores one can calculate various Ranking scores. (RS) characterizing performance of particular runner in this particular discipline.

pick top 4 scores and average them (No Tail)
pick 4 scores and half of the rest and average them (Tail)
pick only A meet scores and perform Tail or No-Tail calculations
pick only A-meet Sprints and perform Tail or No-Tail calculations
Pick everything but Sprints and perform Tail or No-Tail calculations
Pick only Extra Long races and perform Tail or No-Tail calculations
Pick only races of this particular Color and perform Tail or No-Tail calculations
Pick only races organized by this particular club and perform Tail or No-Tail calculations
Pick only A meet races and only one Color of Races, perform "Tail" calculation with them (USOF scores)

All above mentioned possibilities and more are implemented in the O-scores database interface

My JWOC team evaluation

2010-04-16T23:12:00.000-07:00

here is the announcement:
===========================================
Annoucing the 2010 USA Junior World Orienteering Championship Team:

Males

Nathaniel Lyons ROC
Andrew Childs GMOC
Carl Underwood NEOC
Greg Ahlswede DVOA
Ethan Childs GMOC - declined
Keith Andersen USMAOC

1st Alternate - John H. Williams GAOC
2nd Alternate - John Goodwin UNO

Females

Hnnah Burgess USMAOC
Alison Campbell DVOA
Holly Kuestner COC

Congratulation to all of you and the best of luck in Denmark!

Janet Porter, USA Junior Team Administrator
Jeff Saegar, USA Junior Team Coach
Scott Drumm, USOF VP of Competition
==========================================

According to the O-scores the A-meet ratings are as follows

Nathaniel Lyons ROC (M-18), 123.8
Andrew Childs GMOC (M-18), 122.1
Carl Underwood NEOC (M-16), 120.6
Greg Ahlswede DVOA (M-20), 116.1
Ethan Childs GMOC -(M-16), 114.8
Keith Andersen USMAOC (M-20), 110.5

1st Alternate - John H. Williams GAOC, (M-18), 110.6
2nd Alternate - John Goodwin UNO (M-20), 108.6

So it looks like the sorted sequence is about right.
Cutoff is at level of 108.

Who is missing?

Erik Nystrom , (M-20), 136.8 Very solid performance, not too many races (not a citizen?)
Jaxon Rickel (M-16), at 123.7 Solid performance, not too many long races

Jordan Laughlin (M-20), 119.0 Solid Blue performance, many races (YB 1989..)

Huw Stradling , (M-18), 113.2 Shaky performance, one good event year ago (West point), not too many races

I think absence of Erik Nystrom in the team is a definite big loss, but according to Drew he is not a citizen, pity.

Females:

Hannah Burgess USMAOC, (F-20), 95.9
Alison Campbell DVOA (F-20), 98.1
Holly Kuestner COC (F-20), 95.6

Potential Possibilities Missed?
Tori Borish, (F-20), 90.0

My comment at Attackpoint to the US Middle Champs discussion

2010-04-15T12:42:00.001-07:00

I will use this point in the discussion to promote one more time my O-scores database system for those who didn't paid enough attention to it yet.

The system allowed me to predict Jaxon as a top runner some time ago when he had not enough meets to be A-ranked and was running orange.

O-scores is designed specially for those beginners who would like to evaluate themselves immediately and know how they stand to big guys on absolute scale. Doesn't matter what color or what level or event you are running.
I'm still waiting for feet to find time to perform a stress test which will confirm and validate system independently.

In the meantime shows that our best M-16 is still Carl Underwood with Jaxon trailing very close (~125) (link above). And also it shows that they both would beat or match Sergey Velichko and Joseph Brautigam being top M45+'ers (also ~125) (flip age class drop down).

Of course system would require more adequate data stream from local clubs in order to notice local stars and bring them to light. I'm working with event organizers on getting the data, but so far not many of them got interested, event though all what it cost is sending me CSV SportIdent export file.
I wonder, why?

We keep saying that we need to increase population, do this and do that and at the same time refuse to take somebodie's time and efforts to "start-up" some project, even thought to many it might seem useless, but is it harmfull?

Flying Pig XIV analysis

2010-04-12T16:23:00.000-07:00

Official results are at the OCIN web site

There were 32 course offered 10 first day and 11 +11 two following days
In addition to standard WYOBrGRB, there were off-color courses for IS champs. Effectivelly YOBrG were split on two.
I named standard colors as X and off-colors as Y

Here is my analysis.

Absolute All standings

Patrick Goeres (M-21+), Coureurs de Bois *148.8*(1)
Jon Torrance (M35+), OOC *137.6*(2)
Eric Bone (M35+), COC *135.4*(3)
......
Alison Campbell (F-20), DVOA *95.4*(34)

Absolute Women standings

Alison Campbell (F-20), DVOA *95.4*(1)Corinne Porter (F-21+), DVOA *85.5*(2)
Maiya Anderson (F35+), RMOC *80.1*(3)

By course analysis is here

Do not forget to look for interesting subset of by course analysis ( All Women )
As always (!) and (!!) means 7.5% and 15% above the estimate for this runner, and (?), (??) correspondingly below.
Additional mark {new} was added recently. It shows runners whose name mentioned first time this year and therefore their score is not reliable due to lack of data.

Terrain was on average @ 1000 GV/km (it took 10 minutes for 100 point runner to get through each nominal km of the race)

Absolute standings analysis:

Interesting is that Jaxon Rickel again was ver close to the top in absolute rankings - overall 6th place running Green.
Greg Ahlswede running Red is the top Red runner and 7th overall

Joe Barrett (M-14), PTOC *100.3*(27) running Orange and some Green is top Orange runner and 27th overall

Alison Campbell (F-20), DVOA running Brown and some red is the top Brown runner and 34th overall

Zachary Lyons (M-14), ROC *94.4*(36) running Yellow and some Orange is top Yellow runner and 36th overall. Notice that Zach is very stable and didn't lost any point running Orange and not Yellow. This is very promising fact

Top White runner is Lucas Lyons (M-10), ROC *63.8*(128) and 128th overall

Women standings analysis:

Alison Campbell (F-20), DVOA *95.4*(1) is the fastest by far, running combination of Brown and Red. Red performance was worse than Brown, but this can not be attributed to the length of the course, as it was about the same difficulty (GV=4200) as both browns

Top Red runner is Corinne Porter (F-21+), DVOA *85.5*(2) and 2nd overall, almost 10 points behind Alison

Top Green runner is Elena Logvina (F40+), GHO *79.7*(4)

and 4th overall

Top Orange runner is Katie Williams (F-16), OCIN *70.7*(10) 10th overall

Top yellow runner is Nikki Singley (F-16), DVOA *65.6*(16), 16th overall
Nikki tried Orange during the event.

Top white runner Julia Doubson (F-10), BAOC *56.4*(29) was 29th overall

Blue/Red Sprint results uneventful. Sprint terrain was simple @ 500 GV/km

Blue Middle terrain was almost twice slower that Sprint (870 GV/km)
Red Middle as about the same speed-wise
Arvid Jasper and James Mullin can be mentioned as best performers

Green-to-Orange Sprint was about the same speed-wise as Blue Sprint (500)
There was number of significant errors and Improvement by runners with !! and ??

Green Middle produced TOO many exceptional results in both positive and negative directions. Apparently there was something tricky. Same can be said about Brown. and Fundraiser Sprint.
Anybody who participated can comment?

BAOC Shell Ridge 2010-02-14 Personal Note

2010-02-16T10:17:00.000-08:00

I Liked the event very much. Lena went in the morning for a Brown run and I took Ada, Senya and our friends for a White. Even though it was no white by "stroller-can-do-it" standards, this was the most beautiful hikes I did in quite a while. After enormous hike up the hill

There were a lot of nice climbable trees

and spectacular views.

Last down hill was almost scary...

At the far end of the route we got to watch a lot of frogs in the pond.

Lena was on Brown, which was unexpectedly long and she decided to DNF to let me run. I started Green at 12:30, just before the course closing. It was great run, with a lot of tiny mistakes. One of the best technical courses I have run recently. Micro route choices, long legs with a lot of power required, runnable trails and creeks. Great Course overall.

BAOC Shell Ridge 2010-02-14

2010-02-16T09:42:00.000-08:00

This year Shell ridge was very tough for intermediate runners.

( B : 7900, R: 6900; G: 6600; Br: 6400; O: 4200; Y: 2100; W: 1700)

Blue was on the easy side with GV = 7900, while Red, Green and Brown were about the same difficulty, varying from 6900 for red to 6400 for Brown. For Brown this is twice as usually expected!!!
Orange is 4200, Yellow is 2100 and White is 1700. White is twice more than usual also...

Compare event Y2007 here ( B : 9800, R: 7500; G: 4600; Br: 3800; O: 3200; Y: 2000; W: 1300)

Unexpected difficulty of Brown is mainly due to the terrain and not the length of the course.
Terrain difficulty for Brown is almost 1500/km which means 100 point runner (Tapio) would spend 15 minutes per nominal kilometer of the race. Compare with 11 minutes per kilometer on Red and Blue.

Top Performers are marked with (!) and (!!) as usual

Most of the people performed as usual.

Speeders to be mentioned arer Piers Newbery, JOK (guest?) second on blue
Rebecca Minty - first on Red
and William Folette - second on Brown.

White was tough and spread people along the time line. Julia and Hannah finished within a minute. with Hannah being relatively faster.

Extreme performers are below. Any error to be corrected?

BAOC Tilden Park Review

2010-01-29T10:21:00.000-08:00

Tilden advanced courses are usually quite difficult, about 1300GV/km
This year, the most challenging was red with 1500GV/km
Overall courses were about right (GV points) with Blue at 10K , red ~8K, Green 5.5K, Brown and Orange ~3.5K, Yellow at 2K and White at 1.5K

List of extreme performers is below.
Looking at the bottom of the table, I got a suspicion that several people gave their E-dibbers to children or lazy friends (Macleans and Ingert Svard being an example)
Need to be corrected?

Georgia Navigator Cup review

2010-01-28T13:00:00.000-08:00

Main O-speed Table is Here

Performance list is here

Courses Evaluation.

Blue with GV of 9000, was on the easy side
Red and Brown were about average
Green was on the high side

As for the O-speed of the terrain ( GV/nominal km)
All courses Blue through Brown were about 1000points/km which makes 10 minutes for 100 point runner to run nominal kilometer of the distance.

Beginners courses are usually simplere, but in this case Yellow X both days was 1200points/km

Yellow Y was simplier...

By far the fastest is Bonnie Gilbery with Score of almost 69.
Dana Breseman and Becky Forgrave is in tight 2-3 battle with 64 points,
Current official leader Tracy Whelen is 4th speed-wise and will have hard time holding the place when the three above mentioned qualify.

Boys Standings

Jason Allmaras is the fastest with ~93 speed points
Reid Mayfield would be very tight match if not for his poor performance at WIOL #3. He will need to run at least 5 races to have this slow one erased. An given that he already skipped one race - it is a tough task.

Michael Heath can be relatively comfortable at 3rd position (~81 points)

Very close race to watch is between Daniel Cernin and Kevin Wills. Both are about 75 points, qualified and a lot of potential.

------------
JV Girls

The fastest by far is Meredith McCormack-Mager with ~60 points
Becca Cates and April McCabe are next closes ones with ~53 points.
Kendall Rock , Gabby Crawford and Lucy Hill follow very close with ~49 points.

JV Boys

Alexander Cook, Simon Barbe, David Inglis, Alec Glassford, Devon Grove and Mike Klinge all are above 70 Speed points and can win the series.
Stability is the key.

Enjoy

WIOL Series is updated.
Last event is here and Current Standing now looks like this

Compare with official standings here

Course 1 is White through Course 7 - Blue.

I need to work on the search criteria and implement option of choosing races by color. Currently only Age specific classes are available and I must admit I have no clue what is the age of each participant.

Approximately M,F-10 means White; M,F-12 Yellow; F-14 Orange; M14 Brown; F-16 Green and M-16 - Red;
