To make things clear.
Percent only shows relationship between won matches and common matches. So, 92% of 53 means that
48,76
matches (aka kills) were made by player, who died 53 - 48,76 = 4,24 times -- nearly each death player managed to kill about 8 tanks. My common results are higher (89), but have lower percentage (63%), which means I killed
56,07
times and was killed 89 - 56,07 = 32,93 times -- nearly each death I managed to kill 1.5 tank.
I am not sure does percentage really matters for tournament's results, since I already had one tie in sand tournament with UKC_Baller, where he had higher percent but lower results, but still I was put on 1st place. Until future ties, I make a statement that better results take advantage.
