I understand what you're saying Vegas_lover, but here we have Arc who says he wins 45% of his sessions yet manages a six-figure profit over six years (did I get that correctly?) playing 25-cent and $1 VP. So we are led to believe that his 45% session wins on a positive expectation game (one eyed jacks) offsets the 55% of losing sessions.

My first question is why doesn't he have more winning sessions on his positive expectation machine?
My second question is how tight is he on his losing sessions so that 45% of wins offsets the 55% of losses?
