Hmmm, ok, yeh I see where your coming from. The player pool fish factor should really be an inherent sub-bullet point of player pool depth by stake with less onus, as it will be intrinsically connected to the size of player pool. Smaller the pool, the more the need to spread a range of stakes/sites.
I still think Hero objective is relevant though and should trump everything really.
<Small Stakes Hero = Net depositor, breakeven or loser. Never withdraws. Objective: Become a net withdrawer
Mid Stakes Hero = Net withdrawer, winner, never needs to deposit. Objective: Has salary and wants to increase it.
High Stakes Hero = Net Withdrawer, winner, never deps. Objective: Wants to win everything in sight very fast.
Or... Maybe I am being a bit shortsighted by thinking about stakes that are too low to apply this theorem thing as it is intended!!
