Usually get ~75% of what Jamil's calculator predicts. One time I got 51%. I've been plugging in 25% additional cells needed lately and get what I need out of the calculator. I use foil over a flask on a stirplate. I'm going to re-design the stir plate so I can get more agitation without throwing the bar. I tried pumping sterile air into the headspace continuously but that didn't help. I may try what you did with the stone in the starter wort but that is more stuff to clean.
