I made this a few weeks ago and it turned out to be about 8.3%. Mine stopped fermenting after about 10 days using nottingham. I'm cold crashing for 2 weeks before it goes into the keg. I'd probably just test it over the course of a couple days. If it doesn't get any lower, cold crash, keg, bottle or whatever.
But yea, this post should probably be in the cider section.
