Help me out here (if you can without insulting me): doesn't "playing more" get you just that much closer to "over time"? If the math of "over time" gets you to the expected EV (which is most likely a negative expectation), wouldn't players be losing money by playing longer?
If indeed playing more has nothing to do with the math of the game (which says I will inevitably lose), please, please, let me know when the math will kick in so that I will know that I've entered the Over Time Zone and the game at that point is no longer in my favor.
