Oh and guess how I know these figures? Because all these stats needed to put this together are clearly posted on s0br's pool. Nothing is hidden at all I see it all and did the math on my FREE computer calculator.
So from this little common sense chart we can see not only is it possible for a pool to pay the highest reward of any pool out there, not only can you really run a profitable PPS pool but he can also pay a 10% bonus and still have a few BTC left over after its all said and done.
Your arguments are nonsense as they show a complete disregard of long term luck and variance in bitcoin mining.
