These type threads make me laugh. The more bets the better, peorid. Now since you are putting 10 units in to play both ways than it dont matter in your particular question.
But for overall moneymaking purposes the more plays the better. I try and put close to 1,000 plays a month thru, if all are 53%(actually right around 54% for me) plays than each bet is worth around 2% of what I bet. The key is that you are making 53% plays. Anyone saying less isnt taking advantage of what is out there, also realize the more plays than the less luck comes into play. Anything can happen after 10 plays or so but usually a 54% capper hits 54% after 500 plays.
