Somewhere I saw data for Rodinal about how much developer was needed per square inch of film.

My new Nikor 4X5 drum holds 36 oz., and I develop at a dilution of 1:100. The drum holds 12 sheets of 4X5 (240 sq.in)

I'm trying to figure out if I am stretching out the possibility of Rodinal exhausting itselm at 1;100
and if I need more solution, or to cut back to running only six sheets per 32 ozs.

Anybody remember seeing this data on Rodinal needed per sq inch of film. I CAN'T REMEMBER!

Thanks in advance for any help.
