this isn’t my first rodeo. 
if you look back, it appeared that prior to dryhopping, that the gravity stopped at 1.016 based on two readings.
after dryhop it lowered to 1.013, also based on 2 readings.
could be totally unrelated to dryhop or not. i dunno.
looks like you just squeezed out a few more points. did you just raise the temps or did you also rouse the yeast?
Didn’t read all the way back, Paul. I thought it had been @ 1.013 for awhile. I was pretty sure you weren’t a noob. 
Just let it sit at the temp (70df) that I raised to at the end of fermentation - sat for 2 weeks after apparent primary activity subsided. maybe the slow kids finally finished up while it was dryhopping. i wasn’t able to rouse (conical) - need to put together an apparatus like majorvices has to blow co2 in the cone to rouse yeast sometime.
