Imminent Improvements

This road to create and produce an enhanced yet simpler alternative method of evaluating performances in Masters Athletics has been quite long. Already about 4 1/2 years for me so far!

It took quite a while to settle on the methodology, acquire all the data, program the data systems, create the databases and calculators, and then get it all converted into a format that was web enabled.

Once that was all done, I tried to apply myself to looking at all that data and make some sense of it. To my knowledge, there never has been an accumulation of Masters track and field information in one place like John Seto has gathered. To me this was a treasure trove that needed to be mined. I tried to do a bit of that with several posts during the past 18 months.,

But now it’s time to move on. Time for some improvements to the initial concept. I have some ideas.

Here is an outline of what is coming up first.

One of the shortcomings for duncanScore is weakness in the much older age groups, beginning with ages 85 plus.

As you can well imagine, the number of performances tends to decline with 3 factors. Women participate less than Men. Then, after about age-group M and W 50 general participation goes down. Over age 80, very dramatically. And the longer and/or more technical the event, the fewer the competitors.  Think 100m vs Steeplechase. So as these factors compound and we get beyond age-group M/W 80, the number of entries from mastersrankings.com and, hence, the utility of duncanScore, declines.

To remedy as much of this problem as possible, I have added a bunch of performances for older age-groups. Those who have been on this journey with me for awhile will probably recall that the primary data source for duncanSCORE is from mastersrankings.com. The base dataset is the performances from the years 2013-2016.

As part of what I am calling duncanSCORE 2.0, we are adding more years for our calculations. But let’s stay with the older age-groups right now, and let me tell you what I have done to boost the “robustness” of the data.

For the age-groups M-W75 and older, we will now be adding worldwide performances from 2017, 2018, and the available data from 2019 from mastersrankings.com. As well, John Seto, before he took on worldwide rankings from Martin Gasselberger in 2014, tabulated in his high quality, thorough style, US rankings from at least 2008. So, I have included those exclusive US performances from 2008-2012, along with Martin Gasselberger’s international available data from 2008-2012. Additionally, available British best performances from 2008-2012 from www.thepowerof10.info have also been added. So that means age-groups 75 plus have significant numbers of performances from 2008-2019.

All told this more than doubles the performances included to create calculations for age-groups 75 plus. For example in the 100m, W85 performances used for calculations go from 70 to 175. In the 200m,  M90 entries increase from 60 to 175.

I am in the process of redoing the statistics necessary for the calculators to use the additional performances. Over the next few days, these will become available, beginning with the Sprints. So if you are a Sprinter and aged 75 plus, check-in in a couple of days and see if there are any differences.

It should be a better evaluation! Stay tuned.
