… And We’re Back!

Yes, it’s been quite a while.

I’ve been busy these past few months on different aspects of the duncanSCORE, which I hope you will be seeing over the next 1-2 months. There are several improvements coming, and some new features. But given the way I tend to work (if I get bored with one thing, I’ll switch over to something else) and my tendency to get a new idea to work on (i.e. a new shiny object to distract me), sometimes there are delays. But right now several improvements and additions all are approaching completion very much together.

The duncanSCORE is now fully open again, so feel free to try it out and see how well you score against everyone else in the world in your event and age category.

For evaluation of TRACK performances, go here:

Track DE

and for FIELD Performances (Long Jump, High Jump, Shot Put, and Weight Throw) go here:

Field DE

(And if you are new here and are not clear what the duncanSCORE is about as an alternative to age-grading for Masters Track and Field athletes, here is an outline of how it works)

Worldwide, unfortunately,  this is a very unique time. Across the globe due to Covid-19, we are “social distancing” and have to come up with exercise routines at home as our gyms, health clubs, and tracks close. National championships, WMA Regionals, and now WMAToronto2020 Championships have been cancelled. Yet regular exercise is a key to staying healthy and we want to be prepared for that next competitive meet, whenever it will be. Probably you are doing some exercise daily outside. Recently while jogging through my neighbourhood and letting my mind wander, I imagined myself running along the (now likely) deserted streets of one of France’s most picturesque historical villages (see the picture above) that I visited while in Lyon 5 years ago.

It’s fun, too, to note that many of us feed on competition even if there are no track meets. Virtual competitions are all the rage right now. How about some statistical-virtual competition? If you have kept your results from competitions over several years (and if you haven’t, go to mastersrankings.com to get your results), why not use the duncanScore to “compete” with yourself? Here’s how.

Let’s say you are a W60 sprinter, and your best time last year in the 200 was a spectacular 29.11. An amazing time. And as you can see if you use the duncanSCORE calculator

Track DE

that gives you a duncanSCORE of 934 and a percentile of 93  … meaning you are as fast or faster than 93% of the W60s ever in the 200. But you are hard on yourself. After all, you are slowing down. 5 years ago as a W55, you raced the 200 a full 8/10 of a second faster in 28.31. Gosh, that’s nearly a second slower! But are you slowing down at the same rate as your age peers? Lets see. Run that calculator again, this time using the W55 age-group and your faster time from 5 years ago? OMG! Your duncanSCORE is 907 and your percentile 91 … You were (as fast or) faster than 91% of all W55 200m racers. So in fact, relative to your peers you are actually much faster than you were 5 years ago. The best virtual competition. Not only are you beating your peers, you’re also bettering yourself. Congratulations!

So play with the calculators. See how your performances have held up over time. Compare results from different events.

Enjoy!

Now, I think, is an appropriate time to update what’s been happening at the World Champs in Malaga for Canada’s W65 Sprinter Karla Del Grande. I wrote a few weeks ago about her newly established record times, and compared the results duncanSCORE vs Age Grading. You can refresh your memory here.

Karla set a hot Malaga on fire. If you check the results, they list her gold medal time of 14.04 in the 100m, and her 28.83 gold medal winning time as world records. These performances are actually slightly slower to times posted earlier this season, and the applications for these times to be world records are pending. Karla ran a 100m in 13.91 at the NACAC (North/Central America/Caribbean) meet and a 200m in 28.53 at the Canadian Masters Championships. In winning the gold in the 400m in Malaga, she just missed equally the existing WR. Karla ran 68.22.

For the record, this Outdoor season Karla set 2 W65 World Records (pending) in the 100m (13.91) and 200m (28.53), and just missed (0.01 seconds,1:06.22) equaling the World Record in the 400m.

Also for the record, those times have Age Grades of 96.84% (100m), 98.13% (200m), and 96.89% (400m). AG rates her 200m as the best, and 100m and 400 near equal.

The duncanSCORE evaluates these performances slightly differently. 967/97 percentile (100m), identical 967/97 percentile for the 200m, and 952/95 percentile for the 400m. That’s an equal performance in the 100m and 200m and and a 400m about 2% less.

As well, these new W65 world records are rated by AG as inferior to her W60 world records from 5 years ago. Karla’s duncanSCORES on the other hand rate them significantly superior.

I’m biased I admit. But I think the dSCORES are a better evaluation.

The Karla Konundrum

This post talks to how “numbers” can play tricks on you. Sometimes you need to be careful. Age Grade percentages versus duncanSCORE percentiles can sometimes be eerily similar despite the fact they are comparing to different “realities” (in the case of AG against the theoretical best possible performance, dSCORE against your peers across the globe). Let’s do a deep dive on these numbers.

Recently, Canada’s superstar women’s sprinter, Karla Del Grande set 2  new (pending) World records (100m and 200m) for W65 at the Canadian outdoor championships. She currently holds those Outdoor World records for W60. She also came very close to a new WR in the 400 (3/100 shy). This was her first National championship in a new age-group (W65).

The Hytek scoring system spits out these Age Grades (latest 5 year Age Grades based on 2014-2015) for the 100m as 96.49%, for the 200 as 99.16%, and the 400m as 96.96%. All exceptionally high AGs, as you would expect. But note, the 100m is her “poorest” AG, just oh so slightly inferior to her 400m AG (despite the 100 being a WR and 400 not!) The 200m AG is over 2 1/2 pts better than the 100m. And here are her AGs for her W60 100m and 200m world records … 100m – 98.83 and 200m 100.64. So AG says her most recent performances are not as good as 5 years ago. (But in AG’s defence, there is certainly more to come as Karla builds and heads to Malaga for the 2018 WC).

Maybe you’re asking what are her duncanSCORES?  I’m glad you’re asking.

Her 13.96 W65 100m converts to a 966 duncanSCORE (97 percentile). The 28.53 200 converts to an almost identical 967 SCORE (97 percentile). The 400m also rates incredibly high – 952 SCORE, 95 percentile.

The duncanSCORES rate her 100 and 200 performances as identical. The 400, 1 1/2% inferior. AG says the 100m was the poorest performance, the 200 the best. And the 400 2.37% worse than the 200. Her W60 world records in the 100 and 200 also rate near identical scores (954/95 percentile and 953/95 percentile).

So the 2 grading systems yield differing results. AG says the 200 is Karla’s best event, and as of right now, her 2 new WRs are much less than her W60 records. dSCORES indicate that her 100 and 200 are equally her best, and that versus her peers, in 5 years she has improved significantly.

You choose!

But definitely run the duncanSCORE (duncanSCORE) and enter some of your past performances. See what it says about how you are doing (versus your peers in the same age group) then, ,versus now. How are you faring?

Postscript: The week after her new 100m and 200m WR, Karla ran in an invitational Masters 100m  at the NACAC (North and Central American, Caribbean) Championships. She ran 13.91! Primed for Malaga
