Had a home game where both me and my 10% stronger opponent were present. The possession seemed normal first, bonuses were 7% for me and possession was 52-48 in my favour.

Then at the beginning of the second half two new fans came to support me, with my possession bonus jumping to 11% and the disadvantage kicked in. The possession bar switched into my opponent's favour and he began to control the game more. The final possession numbers ended up being 48-52 for away.
