Hi NightStalker,
Thanks for your reply. However, this was also my conclusion. But if one were to define the "best" strategy to play with a value of "1", this quotient would still not be solvable, atleast not through mathematics (but as you suggested, it is probably possible through simulation).
Maybe it's not the quotient we're looking to solve, but rather the "gain" for PE by removing one card from the deck?
