Sounds like the old Kodak "ring around" exercise for ideal exposure and
development. Anytime you change a variable you're supposed to do the
exercise, again. And I thought it was a way for Kodak to sell more film.

And this is the bottom line, isn't it, your working methods give you  
the results you seek.

As far as dynamic range, loss of information, etc. All this can be  
easily tested for those with an inclination to spend their time in  
that way. And it's far easier and cheaper to test with digital than  
with film. Set up a white card with strong texture. Fill the frame  
with it. Make a series of exposures from burning it out to dead  
black. There's your range of stops - right? When out in the field -  
if that range is exceeded by conditions you've got to choose to  
either loose highlights or shadows beyond the range. In the case of  
digital I'll save the highlights every time - because I always find  
stuff in the shadows I wouldn't have expected (ok almost always).
