Response to Minimum amount of Rodinal needed per 8x10 film unit?

I use Rodinal almost daily at 1+100 for 35mm and 120. That works out to 3mls of Rodinal to 300mls of H2O for a roll of 35mm and 5 mls of Rodinal to 500mls of H2O for a roll of 120. The difference in total volume of stock differs due to the size of the container used for each film. NOTE: I sometimes process Agfa APX 100 120 and 35mm togeather in the same container. So as not to confuse myself I still use 1+100 but use the 5mls Rodinal to 500mls of H2O for each roll regardless of format size. I _do not_ see any difference in my negs when I compare the 3mls of Rodinal to 300mls of H2O negs to the 5mls of Rodinal to 500mls of H2O negs...jim
