Brewin@ up a storm Sat In roulette they pay 35/1 for a single number but there are 37 numbers - 2,7 % edge
in jumps say we rely on the smaller figure of 10 per cent fallers or pulled up bookies immediately have 10 per cent edge on every race thats a huge edge some tracks its nearer 20%
just a thought as stated before if you pick a solid jumper you decrease that edge
