Cal,
Obviously the electronically timed shutter of the F3 should be more accurate than the F2's however Sover adjusts the F2 for 1/3 stop accuracy at all speeds which is more accurate than they left the factory. He only ever had one of mine that could not be 1/3 accurate at 1/2000 because some idiot had over tightened the roller tension spring. Furthermore an F or F2 should never be left in the cocked position as this will adversely effect these very small springs and render the speeds inaccurate.
John,
The point I was trying to make is that sometimes mechanical cameras need adjustment.
About 6 years ago I had my Wetlar M6 overhauled by Sherry a factory trained repair person. To me there is a big difference between a CLA and an overhaul: meaning new parts and more disassmbly. Recently I had Nippon perform a vertical adjustment to my rangefinder and they recommended a complete overhaul because my speeds were off and were out of spec. Anyways I was not surprised since the old M6 over the years was shot both regularly and heavily like a pro camera. I ended up refaining from getting another overhaul and rebuild because the camera still shoots fine, although the speeds might be off. I'm thinking it is most likely its the fast speeds run a little short because the slow speeds sound spot on to me.
Thinking this is what happens to F2's, and that is the context of what I was trying to say.
