Nerding Out: LCM National Age Group Record Progressions

Yesterday, we published our SCY National Age Group record progression list, and got a ton of great feedback (thanks to all who helped!).  Today, we’re posting our LCM NAG record progressions the same way we did yesterday.

Once again, we have embedded a spreadsheet below from all of the existing data we have available.  In addition, we included the swimmer’s total number of Olympic medals in the righthand columns.

We’re expecting there will be a couple errors like there were yesterday; as we previously stated, our resources were limited (available meet results online, USA Swimming’s time databases, and existing USA Swimming top 100 documentation).  See any errors or omissions?  Feel free to leave them in the comments section, and we’ll address them/extend our gratitude for the assistance.

Again, if we look at the number of Olympians like we did yesterday (counting each swimmer once per age group):

For comparison, here’s the chart from yesterday’s SCY progressions (with one change, due to the addition of Elaine Breeden in the 17-18 girls 200 fly):

We’ll do more analysis on this later, but the most interesting thing as first glance is that for the 13-14 and 15-16 age groups, the number of age group record setters in long course meters who went on to be Olympians is actually less than the totals in short course yards.  While the LCM numbers surpass the SCY ones in the 15-16 and 17-18 age groups, you would think that, given just how different the two courses are, we would see more LCM record holders turning into Olympians at a younger age.

Stay tuned for our multiple-entry NAG record listings.  They’re quite a bit more involved (we’re attempting to count every instance a record was broken, although we’re missing a lot of data from the 70’s and 80’s), so expect them either this weekend or early next week.
