Tilastopaja.net is a pretty thorough database, but Ken Young's records might be more comprehensive at least back to the early 1950s. Also, I know that Ken is into developing machine learning.
From earlier Trackbot for Coe versus Ovett. Did they really only race each other 5 times on the track? 4 of them at the Olympics?
Is it only international level races that are in the database? Surely there most be a lot of domestic level races missing?
Moreso the fact that the DB isn't meant to be comprehensive before 1998, it only has the Olympics and other major international competitions before then.[/quote]
