If nothing changes and he's 74.2% to win the first session, then he's 74.2% to win the second session and the third and the fourth. So... doesn't that mean he's 74.2% to win it all?
Let's use coin flips. LOL
If Rob has the skill to flip 74 out of 100 coins as heads shouldn't that skill be the same in each session?
Let me use an AP example:
If an AP says he's playing a game that gives him a 100.7% return on the first hand plsyed, doesn't he have the same EV on the second hand and the third and the fourth....?
