If in September 2015 I started with 500 euros and in September 2016 I have 15.000 thousand, it means that I weigh correctly whether I lose or win. Now if we wait to say if 1 match is value it is useless (lose, win).
If within a year a player does this, with over 1000 bets (and I say a little), then we can really talk about value. The player who wins the rake and the book is systematically judged based on the time and number of bets. What do they come out of? Are they really valium bets and winning players with method and system? or the jackpot from the first spins?
