Hey skinnyman,
Unless he's laying tiny shots on the tennis then a 50% strike rate just aint enough
I've3 put this on hold for now but long term I will be coming back to it, I may even look at the competitions on a few other sites this weekend to get the bets ticking over again.
The real problem as you say is being on the computer all bloody day to get the value out of it, impossible for just about any of us, the RP naps table could be the way to go but then theres far too many big losing days to do it with a normal persons betting allowance. They are all up in advance and the BF horse racing markets are getting better in the mornings than they once were, thats whats going in its favor (if nothing else).
