Since I've searched for a starting point for this new film and have not found one, I did a bracketed first test roll in replenished Xtol, 11 1/2 minutes at 72F. It came out a bit over developed, I'll probably cut it back to 10 min at 72F for the next roll. I'd thought I'd share my times in case anyone else tries this film and needs a starting point. More on my blog four-silver-atoms.com. Looks similar to what I remember APX 100, but not exact.
