What I’ve Been Working On – The Dashboard

It’s been a very busy time here at duncanScore.

As you might remember, duncanScores are calculated from mastersrankings.com performances from 2013-2016.  I am in the process of adding results from 2017-2019 and recalculating the averages and standard deviations which will yield updated/revised duncanScores.

I am pleased (though not surprised) that with the addition of 2017-2019, so far duncanScores change only marginally. So I am confident the process is solid, and over the next 1-2 months I will be posting updated calculators.

And there are a few other improvements I am hoping to implement. The first is a kind of dashboard for results. Here is how it may look. As an example I am going to use my 400m performance the summer after I turned 65 to illustrate it.

That year my best 400m performance at 65 was 68.53 seconds. Using the new (yet to be posted) updated factors, this gives me an M65 duncanScore of 800, meaning that at 65 I was as fast or faster than 80% of M65s in the 400m. Not wonderfully exceptional, or good enough to make the final at a WC, but a good shot for the semi-final. See here why

By the way, the score of 800 is very close to the “original” duncanScore calculator (with only 2013-2016 performances) which yielded a 793 score. So adding 3 more years of results for the calculations made no material difference. The dashboard for the 5 year Age Group (M65) results would look like this.


But as the announcer on the television infomercial inevitably says, “Wait … there’s more!”

Recently turning 65 would give me a bit of a “youth” advantage over most of the other M65s (aged 66 to 69). How good was I versus all the other 65 year old 400m men runners?  For that we would need a duncanScore for individual age-years.

And here it is!  …

So there you have it! While I may have been as fast as 80% of the M65s, I was only as fast as 75% of the 65-year olds. And with this new metric, as I age, year by year, I can truly see how well I am keeping pace with my age specific comrades.

“But wait!” says the infomercial announcer … “we have more!” My 68 second 400m was approximately the average time for a 57 year old competitive Masters man. I could say, then, that my “running age”, or what I’m calling my Athletic Age, was 57.  I might say I was running 8 years younger than my actual age (see the yellow circle in the chart).

That is another metric worth tracking over time.

So that’s what I’m working on.

The next phase is incorporating mastersrankings results from 2017-2019 and updating the factors for upgraded duncanScores for all 5 year age groups in all events. After some more final checks, I will release new 400m factors for the calculator next week.

After that, the big job will be providing factors for individual age years … so you can get your duncanScore for your event by your age year. Then the Dashboard.

  1. Hi Dunc,
    Very interesting. I like the idea that what performances one does at a certain age can be compared to one’s actual age. One can be performing at one’s current age; or at a younger age; or, heaven forbid, performing at an age older than one’s current age. The one thing about this process that I have trouble with is that this relies on stats from masters runners who can record a performance. I have to remind myself that this is a ranking of athletes who can manage performances. It is not a reflection of a ranking amongst all people in the world who of that age group. For example, anyone who at age 65 can get around the track for one lap (400m) is probably in the top 1% range. Whereas, your system gives one a solid feel for how one is performing amongst active performers throughout the world (which is very valuable to us).
    Does mastersrankings include all international events? Some Senior Games results in the US don’t get included. I do realize that some state games don’t report results well. I suppose that any results that National Masters News reports would be included. Keep up the good work. It will be neat to plug in current results into the duncanScores in the future.

    • Thanks Tim for your thoughtful response. There is no question that the data used does not represent the general population. We are a very unique subset. At the same time we are a very competitive lot, and always wondering where we stand versus everyone else. My “Athletic Age” stat is my attempt to create something meaningful for non Masters people. I’ll give you my reason why. A few years ago when I was slowing down so drastically I tried to find out the reason. I changed my training, even switched coaches. No improvement. I then tried doctors and other medical professionals. The first reaction was, of course, “well how old ARE you?”. I showed my rising times for 400 & 800, and worsening age grades. But all were meaningless to them. As I calculate it now, every year during this time, my “Athletic Age” was rising 3 years. I was aging triple what is average or normal. Perhaps they might have been able to grasp that metric and realized, yes, there was something wrong.

      I can’t say for sure if Masters Rankings has all international events … probably not. But John Seto does try very hard to get as many meets as possible. There is, too, a self input option.
