I have some experience. I am shooting Scala @ EI 100 and developing it in Pyrocat-MC 1+1+150 for 30 min (20C, 68F) semi-stand. I have tried to shoot it @ ISO 200 and developing it for 45 minutes with agitation first 30 seconds and then on 15-th and 30-th minutes (the same dilution and temperature). The negatives are printable but it is not really ISO200 film when processed as negative.
I hope this helps
P.S. Attached image was shot on Scala @ EI100
