Response to Minimum amount of Rodinal

What happens if you have slightly insufficient developer? I suppose development proceeds normally until exhaustion approaches, then what? I recently tried to ascertain whether 250mL of normal PMK was really adequate for a 36exp 35mm film, and I could not tell the difference between it and using 500mL. I judged this by some zone_1 frames at a range of speeds. Exactly the same, as far as a "proper proof" was concerned. I have no access to a densitometer. I did not test for heavily exposed frames. If those were the only ones affected, maybe it would be useful rather than a problem to allow exhaustion.
