Some people need the technical aspect in order to continue with actual photographing. I see nothing wrong with it. But, there is a point where you do get too far into the technicals and what counts (the actual photograph) begins to suffer, not only from lack of time but the brain begins to think in some skewed directions. I'm at the point that it should suffice to test materials with equipment for normal exposure and +/- (1 and 2) developments without trying to break it down too far. So, once I'm convinced my testing gave me consistency, I'm good for a long time.

At the end of the day it is the actual photograph and how it is received, especially by the photographer himself, who should be the ultimate judge of his own work (unless of course, it is commercial work that puts food on the table, then such standards don't often apply).
