With PPS, fee or no fee, you mine at a flat rate. So if, so called, luck is good you loose if it is bad then you win or least break even.
The
law of large numbers means that in the long run, you will never have consistently good "luck" anyway. The only potential gain from non-PPS is
short-term good "luck". Also, you don't
lose it by using PPS-- you simply don't get paid an unfairly high amount. PPS pays you what is "fair" for each share. Do you complain because blocks only pay 50 BTC, and not more when you're "lucky"?
I have no problem with PPS model/pools.
A person was making a point that it is somehow wrong to use anything but a 0% PPS pool. I was just trying to explain that PPS is just a flat rate payment. A proportional type payment varies from round to round according to how many shares were contributed. There is nothing "wrong" with using either method.
Good Luck just means that your GPU got some hash's in on short blocks so your pay per share is higher. There's nothing wrong with that. No I don't complain that there is only 50 BTC pay per block. But I guess some people do because some pools pay out more than 50 BTC per block.
How do some pools plan on staying in business? I prefer to use pools that have a clear and disclosed plan for maintaining sustainability.
