I was thinking about that too, but it isn't quite the right way to isolate the effect of tribe because it compares across two different definitions of tribe, college vs country, instead of comparing otherwise like events, one with tribe and one without. A better, but imperfect way due to the school aligned RTC programs, is to look at freestyle without tribe (BTS, Fargo (aka pre-tribe?), US Open, OTT, and the like) versus freestyle with tribe (Olympics). And there the contrast is stark.
