See. I have a problem with the AT LEAST part. a party frat would have so many strangers drifting through that it would weardown the threshold even if it where only 1.
And if someone where selling drugs (not an uncommon occurrence), or conducting any form of business out of the frat, then that would destroy the threshold. That is the exact reason that the Sells lakehouse didn't have a threshold. Victor was running his business out of it.
I agree that most frats would have 1. a superparty frat (or one that a high volume campus drug dealer lived in) wouldn't have any. and MAYBE one or two others per campus would meet the requirements to have higher, but again, they are the exception, not the rule.
