On a happy note, I got 2.5 inches from a hot soak and drip dry. When I saw a report of 2 inches shrink from a full length inseam with time in the drier, I get a little nervous. Percentage shrink may be a better metric to use than inches of shrink. Percentage-wise, I got the equivalent to 3 inches after hemming.
Leg shrinkage is disappointing given the Self Edge claim of 3 inches that I based my hem on. You'd think such a small, expensive batch created by hardcore denim nerds would have some better testing done on the unique fabric. I'll reserve my final judgement until I can try mine out ¯\_(ツ)_/¯
