Just wondering what is the collegiate cutoff date for records each season, as they are saying Kyle Merber set the american collegiate record in the 1500. I know for sure there have been times set better in the summers even just recently like Wheatings 3:30, Centrowitz 3:34, or even back when Gabe Jennings won the OT's in 3:35.21 as a sophomore.
Anyway, it would be interesting if there was a list with In-season bests, and complete collegiate bests.
