That's not how it works. The idea is that you need at least one fat guy on the team, but having more than one does nothing. The second factor is GHR, which should be as close to 1 as possible, ideally 1. Everyone on Na'Vi has average hair, so each of them 0 points. 5x0 = 0 points. Vitality has rpk who gets -1 for trash hair and shox gets +2 for really good hair, the rest of them 0 for average, giving a GHR of exactly 1. So Vitality has an advantage.
