Strategy for altered payouts ($100)

[HeavilyArmed]

I play live casino SNGs for $100+$20 and $200+$25. The rake is awful as is the overall play, no better than Stars $6.5s. The twist is that the house steals $50 out of the 1st place prize for a bogus jackpot that has a real EV of maybe $5. So the payouts are 47.3%, 31.6% and 21.1% in the $100 event, somewhat closer to normal in the $200.

What, if any, changes might you make in adjusting?

Oh, and don't forget to tip the dealer.
