Maybe it is thay way you talking about crackfoo, but I am not a humanist, I prefer numbers. I think that 1 gpu could calculate 1 algorithm/coin a time so when it gets a job for 1 coin, will be not calculate another coin in the same time. And following, if it get a job for less profitable coin, will not get a piece of cake from more profitable coin when this block will be solved, because it wasnt participate in cooking. If those last 50 earnings are really for free, this is great. But I cant believe that it is exactly that way going
