If the fee for Pay Per Share (PPS) Method is 7.5%, is it correct that if the pool's luck (hypothetically) ran at 92.5% forever, than the PPS method would break even?  Asked another way, if a miner is using PPS, and the pool luck is below 92.5% for an very extended period, would the miner make more than if he was using PPLNS, for the same extended time period?
