I mashed at 151F and used yeast nutrient, oxygenated with pure o2, pitched and fermented at 68F using my Ranco controlled refrigerator. I have absolutely no temp fluctuation. There isn't anything you did that I don't do.
I used 2 tubes of yeast and built them with my stir plate into a half gallon starter for 10 gallons of beer. If there ever is a next time and I don't think there ever will, I'll double the yeast.
It is more than a finicky yeast, it's weak and unpredictable, unstable and unreliable. Not worth chancing another under performance. 6
