Quite a bit less time than my favorite film Neopan 1600 which gets 12 so this across stuff is a different ballgame. I think it's the iodides, a tab grain deal. My Neopan 400 gets 13 i think. Some very nice 35mm looking negs and contact sheets I'll print this week. I bought a brick of the stuff in 120 but not shot any of it yet. I agitate once a minute by rolling the tank on my Wetsink back and forth gently a few times. A piece of masking tape makes sure the rubber lid does not fall off.
