Fair question Bobby. We have percentages based on hitting 9 and we have percentages on hitting 10. We can't hit 9.5 of course. We had to hit 10 at a Posted line of 9 and therefore the % Bet was lowered. A move from 9 to 9.5 would have eliminated the bet Totally since the 9 Push would not have been in action..
A move off an EVEN Number is more important than off a HALF Number but the move off the Half is still significant enough some of the time to lower the wager..
