I assume normal betting limits apply. Your bankroll will mostly hover at break even.

Sure if you use progression, the swings will be more pronounced, but youll end up the same place. Progression is a like a loan that eventually gets repaid.

I disagree. I think a player that uses a positive, up as you win, progression would fair alot better than a flatbetter or a negative progression player.

On a non zero wheel, the chance a flatbetter will win or lose 200 units will be 50%. A positive progression player will also lose 200 units 50% of time, but will win 500 or more units the other 50%. For the negative progression player, it will be the opposite...losses will be greater than wins.

Assuming all 3 players play the exact same strategy, for the same duration. If we were to look at 100 samples and compare, flatbetting will hover around even. Positive progression player will see greater wins than losses. Negative progression player will see greater losses than wins.
