Nightowk there is always going to be losers, that's why it's imperative to get BOG and get them early.
Here's my stakes/returns for today and you'll see what I mean:
Staked 26pts / Returns 30pts (1pt per £5)
Realta mi Croi - Backed at 10.0, went off at 4.0 and won. There's £30 / 6pts extra
Marie deja la - Backed at 4.5 but drifted to 5.5 (BOG) There's £5 / 1pt extra.
I backed 26 horses and only had 5 winners yet still made profit. So it's not all about strike rate/win percentages
