It would be fun, but we just don't have the data. People could submit it, but we have a hard enough time getting other more important info that we want! Shane would probably lobby for a column showing races attended / completed / won!
Funny enough, managing membership for several years, I've noticed that a lot of people skip years and then come back. For example, was a member in 2011 and 2012, skipped 2013 and 2014, back in 2015. (Probably that Peace Corps stint in Uganda, eh?!) I think online membership payment will help with renewals, and already many folks have used it.
