plus there are multiple group at each level bracket, and they are big brackets.
I have seen level range of about 40 levels in one contest, and I only looked up a few players. Basically I was looking to see how many girls the top guys had... to see if I could compete at leveling them up in that contest.
Yeah, never max all ur girls without checking the other players. I'm sure I have one girl in my harem sitting at the same level for 55 levels. Admittedly I have had the locked out of contest bug on and off for a while, and for the ones I have been in, haven't needed the extra xp yet.
