How to Use Personal Speed Point 
M E CARBOY  0:02 1 Sep 02 
Phil,

I have read your article on personal speed point and your commentary makes sense. Once we have identified and selected our speed point for a given developer/film combination, how do we then use the adjusted film speeds? Does the new ExpoDev carry this information over so as to preclude the underexposure/overexposure that might occur if we merely assumed the rated speed was in fact correct for all developer/gbar situations?
