I would have thought not, but on my most recent casino run I had an extreme experience. Had $15 in free play and went to a quarter 9/5 DDB progressive with it. Hit a FH on my first hand, but noticed the machine was set on the slowest speed. Raised it to the middle speed, and proceeded to lose the remaining 12 hands. Cashed out $10, which was less than my original hit.
Probably just a random drought unrelated to the speed setting, but is certainly cause for wonder.
