Did an all Citra IPA yesterday that's chugging at 64 as well as a Blonde ale that's just getting started at 62. Tried to pitch roughly 1 mill cells/ml wort/degree Plato for both, but surprised the 2 degree warmer IPA took off so much quicker.
What method/formula do you use to estimate your cell count? I'm familiar with MrMalty, and the Wyeast web page gives some advice, but I'd like to hear what others do.
