No Mike, you should keep the same PSP. In other words, if you have calibrated your set up to give EFSs with a PSP of 2.4 you should keep using this set up in the same way, the system will account for the variance in film speed for your new film. You should not mess with the PSP unless you want to have the values moved up or down the curve, the point should stay the same with new film tests if you have calibrated the set up to give a 2.4 PSP.

PS, got your e mail but was giving a workshop, I will get back to you soon.
