One interesting implication of that 10% rule is that if either team happens to get a good early start or if the skill gap is too large, then their markets have a high risk of being voided.
On a side note i had the exact bet they voided in a 4 fold combo bet which was NOT VOIDED as it was was a smaller bet of the several bets i made. So in a nutshell , the biggest bet you make they will void during the game play LIVE when the bet is winning.
