XTOL and Plus-Xgreenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
I have had great luck processing my TMY and Delta 100 over the last few months. For my process/equipment I seem to get a tiny bit more speed that the EI on the film box by using XTOL 1+2 temp/times as recommended by kodak and good contrast. When I decided to try XTOL with Plus-X at EI 125 (usually processed in ID11) my negatives seem really thick in the shadows and midtones by about a stop maybe a little more when processed using Kodak recommeded time/temp. The negatives are not overly contrasty. Plus-X seems to be more like EI250 or my meter suddenly became broken. Has anybody else seen a dramatic increase in speed using XTOL 1+2 and Plus-X?

I haven't tried it with Plus-X, but Xtol at 1:3 gives me a 1 stop increase in speed on Tri-X 70mm (400 ISO).
I would not be at all surprised to see the speed gain you are talking about.
