That means it has no effects whether i have 1 worker with 2 different gpu in the same pool versus 2 workers with 2 different gpus in the same pool?
As far as I can tell, however, someone might chime in later on and tell us that each worker at their pool gets a different group of hashes, meaning multiple miners on one worker leads to a possibility of stale shares. I can't say that I know one way or another. The first pool I used said I needed to create a worker and I could use as many miners as I wanted on it, but didn't provide any technical info for or against doing it that way.
