Let's assume that the final scores are correct.
Buchholz score (http://ru.wikipedia.org/wiki/Коэффициент_Бухгольца):
Roland: 1 (Wowa) + 2 (Pit) + 2 (Stinger) + 4 (Bayazet) = 9
Vitalik: 4 (Bayazet) + 0.5 (Aldegir) + 1 (Lexa) + 2 (Pit) = 7.5
Medium: 1 (Napalm) + 1 (Lexa) + 4 (Bayazet) + 2 (Stinger) = 8
Mee: 1 (Merlin) + 4 (Bayazet) + 1 (Alone) + 2 (Preds) = 8

Total (counting winners based on Buchholz score):
2. Roland
3-4. Medium, Mee
5. Vitalik
It seems Vic was mistaken, thinking that everyone had the same Buchholz score. Question for VIC: there's nothing in the regulations that says that if the scores are equal, the winners will be determined by the Buchholz score. So, why did you calculate it?

P.S. Heartfelt congratulations to Dima-Roland, I'm sincerely glad he took second place, it's a pity he didn't take first, because I was rooting for him the most.
Bayazet deserves mega-respect! Alexey is a true champion of the CIS and the strongest hero player of our time! I'm glad he proved it with his actions!
