so, who's method of aeration do you guys use? Jamil calls for much higher cell count then Troester. Not sure who to go with....

Troester for me.

I've done cell counts on yeast I culture and I find that with my process and equipment that I am consistently a 10% lower cell count than what Troester's calculation is. That said, Troester is what I use, but I don't think either calculation is wrong... without cell counts its all estimation anyway.

I go with Kai's calculations. I just finished off my starter, started with 40B cells from a 50ml starter. Kai's tracked my step ups all the way to the 3L starter ending with 667B cells (counted), Kai's calculator had me at 673B.
