GAC, 2.5 mil difference against opponent

My last GAC week every one of the other 7 in my bracket had 2 more GL than me or 2M more GP. First autoset and I won handily. 2nd player had 2M (6M roster) more GP than me but 0 GL. He was a garbage player, won easily. Last guy had 2M more than me and 1 GL like me. I won fairly easily.

Skill rating means something. I expected to go 0-3 but swept the bracket.
