Problem is that to prove yourself you would have to post for a couple of years just about, I mean I'm into place betting and just looking at some recent results there was a run of 19 hits, on the same page there is a run of 4 outs 1 hit 3 outs 2 hits 3 outs, i.e. only 3 places out of 13 bets. So depending on when you decided to "prove" yourself you could look very silly or very clever.
Truth is this particular plan hovers at around 70% hits (places that is) over a long period. if only we knew which 70% eh?
