So, we run a tournament with this system, what are we going to limit it to? I say 5, partly because in the interview I heard on the 11th company, that was what I heard as one of the commonly used #'s. Also, we're new to this, let's start off slow, but 5 should weed out some of the crazier stuff. We should also give bonus points for the comp differential, so there's still a benefit for having a lower score.
(And, yes, my basic list scores a 5 but that's not really why I'm suggesting this number -- I could shave it down to 3 easy enough)
