How fast are you? Well, you know your absolute performance, from your race time. The clock doesn’t lie.
But as Masters, while we need to know the absolute time of our performance, given Father Time’s unflagging ability to make us slower, we tend to also prioritize our relative performance.
In other words, it’s how we ask the question … and how we frame the answer.
In the duncanSCORE how fast you are is expressed as a percentile of your age cohort. The percentage of your age-group that you equal or outperform.
In age-grading it is a percentage of the theoretical best possible performance for your age group and gender.
The Age-Grading process (I’m using the “Howard Grubb” web site calculator here http://howardgrubb.co.uk/athletics/wmalookup15.html using 2015 factors) also will give you another relative look at your performance, an “Open” result (see point 2 below). Didn’t we all enjoy seeing what Ed Whitlock’s road race times “converted” to the times for Open runners?
So, could you compare your performance to an “Open” time?
The Age Grading process works like this:
- Your time is divided by the “Age Standard” to arrive at your age-graded percentage. The age-standard is an estimate of what the ultimate possible performance is. The “ultimate possible” is usually better than the WR at the time the tables were created.
- An “Open” result is created by dividing the “Open Standard” (the Open WR at the time the tables were created) by the age-graded percentage.
duncanSCORE “Open” Calculations will be different
The duncanSCORE is also going to provide equivalent “Elite/Open” times in the upcoming weeks.
But the process will be different. (It’s taking a lot longer than I expected to pull this together, but then everything on this project has been taking more time than I expected.)
Our “Open” calculations will be based upon the World Athletics (formerly IAAF) All-Time lists, supplemented by WA performance lists from 2016-2019.
What does this mean? How will it work?
These World Athletics lists will be pared down to construct a perfect (or near-perfect) bell curve. After all, that’s the way duncanSCORE works … putting Athletics performances on a bell curve. This WA bell curve will be matched with the bell curve from your age-group/event. Your bell curve result (ie the number of standard deviations away from the average) will be matched with the same bell curve result for the Elite/Open results.
The point is not to say this is what you should have run back in the day.Rather, it is to say
the duncanScore tells you how you rate against everyone in the world in your age-group over time. Here is what that equivalent rating is to the actual best in the world all-time.
We are calling this facility the Juvenator, and next post I will show you how this works, beginning with the 400m.
In the meantime, don’t forget to see how your track performances measure up against your age peers. Try it out here …
