It is worthless me answering that question if you believe that the true intrinsic value of an ATS bet is 50-50.
If you told me someone was claiming to be 63.8% correctly calling the side of a coin, over a period of 10,000 coin flips, is essentially impossible.
Sports betting on the other hand? Whilst highly improbable, it is far from being as impossible as a coin flip. Unless you are telling me that human beings can be quantified into "certainties", or that any one bookmaker/line-setter can account for all the thousands of variables that are involved in a human playing a sport. Some people tend to forget that lines are set, most often, to induce a 50-50 split between public perception - NOT to set the true probability of an event occuring.
Anyway, go and read post 5 yourself. He said he has hit 63.8% of his bets. No where does he mention ATS, nor does he mention that the bets were at a -110 line.
