As Grand Slam said it is valuable if you can get a free push to U9.5 or 7.5 rather than 9 or 7. As you can see those two numbers account for over 20% of all games. If you just wait and take the free ride on these two numbers you should turn a profit. When you look at the individual numbers when a game is lined at either 7 or 9 the % is even higher. Good luck sir.
