I'm not following you. When you send the film to Main, do you tell them the EI you used? When I contacted them, they more or less told me that it would be hit or miss, but for TMX, they had already determined that the "normal" EI would be 50 and that 100 would involve a one stop push. When I cross-processed TMX using Duggal in NYC (also a Scala machine), I recall that TMX did have to be shot at an EI below the ISO - I kind of remember it being EI 25, but I could be wrong.
