I can relate to this. I've just tried a couple yeastcakes recently and the first was churning within 3 hours, and most recently I noticed churning in 1.5 hours. Aside from the cakes, the best times I can recall with liquid yeast starters is in the 6-7 hour range. I figure as long as I'm seeing some activity within about 12 hours I'm pretty happy.
