After 11 days the SG was 1.017 and it slowly chomped on those last points over the next three weeks. FG of 1.002 after a 5 week primary.
I never experienced a stall, and I think the key was a huge starter, yeast nutrient, ramping up the temperature, and patience.
Uhhh...if it needed 5 weeks to reach FG, then you had a stall.
This strain should take 5-7 days to reach terminal gravity (< 1.005) with wort of modest density - if the fermentation is handled correctly.
