Hey William, here is what I mean by juice on win bets..... you can convert odds into percentages, and if you have exactly 100% total on all bets that means there is no juice.....for example......lets just say for conversation sake that johnson is -300 to win the race....that means he has a 75% chance to win.......the other odds for the other drivers should add up to 25% if you have no juice......but usually you will find that if you do the math the percentages equal somewhere around the area of 115-120%, which is about the same juice you will pay for a matchup!
Good luck and keep giving winners!
