I've moved to Rosetta for a while now until a project comes around that i want to crunch. I got 4 machines doing a 50% Rosetta and a 50% ABC share.

Does anyone know if the longer the Rosetta WU is, the more beneficial it is to the project? I have noticed that it does more models the longer the WU is but does it learn and get better with each model or is it a shot in the dark with each model?
