I run slowdown a lot with the press. I think this is somewhat unusual, but my pressing teams have a tendency to foul too much (maybe I just haven't recruited really good defense yet), and if they get in foul trouble, my bench stamina isn't good enough to avoid playing a lot in the red. So I slow it down to minimize fouls. It definitely works for that. The question is whether it's worth the other costs of slowdown (for instance, higher variance)
