Please feel free to correct me, but, I thought that you needed maximum attendance to get 5% possession advantage. I have just played a game (nice and easy 6-1 win. so no complaints) but was surprised to see that my opponent had 5% possession with a crowd of 51K out of a max of 76K. If my crowd is down by more than 2K from maximum then I lose a % of possession/ Confused.com
