Regarding Jek's/BW's break-even points for BBJ (long)

[J_B]

This is really two questions:

1. When is the amount I pay towards the jackpot +EV for the prize?
2. How does it affect my win rate vs. a normal non-drop game?

While #1 could be +EV, it could make #2 -EV and vice versa.

Think of it more like a carribean stud jp drop. At a certain point it becomes +EV. Same idea. Or for that matter, the lottery.
