It's not going to flocculate if it's riding the tilt o whirl, nor will a krausen easily form on the sides either.
But just stopping the spinner and checking after an hour or two to see if the yeast has fallen, or even is there's a lot of suspended yeast particles is enough.
Normally i agree, Revvy. But in this case he has a 400 mL starter. He didn't double his yeast count or anything that significant. I think its going to look a lot like it would if nothing had happened. 125 billion cells in 400 mL is probably going to look a lot like the 100 billion cells he intially pitched in 400 mL.
So while I agree that his starter is done and all is well, i don't think that the visual test would confirm a lot in this case. Just my opinion.
