15hrs is really a long time consuming just for gambling i guess you already got a lots of patient considering that you win after that long period of time, a lots of gamblers really got greedy when they seen some potential forgetting about the main goal why you first create your strategy, maybe its really depend on the person itself to win from it especially in the lone period of playing.
