You probably missed the “if” conditional in my sentence, so let me rewrite what I wrote in a different way: If I were taking sky-high-fees at my pool and still deliver comparable and/or better after-fee profitability than other profit-switch pools which take 1-3% fee, then it would mean either 1) they're incompetent because their results after 1-3% fee are comparable/worse than my results after sky-high-fee; or 2) their results are also higher but they silently cut more in fees that they claim.

Under no circumstances I am claiming or suggesting that any of these two variants are happening. It was just my way of writing that my upper fee cannot be very high, because I either would need to be some kind of a genius or all other pools would have to be stealing. While I  consider myself pretty smart dude, I believe none of these two is true so there's a third variant left which is my fee isn't sky-high. I'm sorry for misunderstanding, English isn't my native language. Please give me some time to test and tweak this progressive fee idea before I settle with some final model.
