Safale US-05's alcohol tolerance?

Just brewed a stout with an OG of 1.131 and pitched S05 - already down to 1.081 in three days.

I hit 13.5% on my RIS with a single pack. The force is strong with US-05.

But it does slow down at higher alcohol concentrations. I've got it chugging away at a Bourbon Stout now for 1.5 weeks that started at 1.10 and it's only down to 1.029, right around the bottom inflection point in the curve.
