I can't remember what casino it was that Wizard reported on, that had the sequential Royal bonus. Everyone playing this machine was 103%-105% (IIRC). Thousands played, one person won, but EVERYONE is +EV. Variance is a Bitch.
Same example with the linked Ultimate Texas HoldEm Bonus Jackpot. Earlier this year, Wasn't it around 105%? (+EV). Tens of thousands played. Only 1 person REALISED the Value (6-7 figures), but all were +EV. Variance is a Bitch.
Due to variance, Expected Value is eventually realized, by someone, but that someone may or may NOT be you!
Remember, EV can take longer than the human lifespan to realize the actual value. This is why variance matters!
