You were very clear in your original description that the 1.5 was not the time since rennet, but the additional time. I just wanted to make sure that when people saw the 1.5x they didn't skim over the detail and make a mistake! (because, I confess, the first time I read through I was thinking 1.5 as the floc multiplier, and was thinking wow, that's the shortest I've ever seen! Then, after slowing down, and actually reading what you've written, I realized my mistake).
Anyway, this is a great thread. Wonderful details and hints. I'm suspecting a large number of reblochon threads to be starting very soon.
