DEAR BOGDAN
I used to have a 3 1/2 gallon D-76 line in my film darkroom in my
NYC studio from 1974 until I moved to Barbados in 1993. I replenished with
3/4 of D-76R for every 80 sq in of film. Ever 100 rolls I removed 1 gallon
of dev and added a gallon of fresh D-76. After about 400 rolls I mixed the
entire 3 1/2 gallons fresh. As Richard can attest, I have no idea what the
composition of that soup was after 100 rolls but I got brilliant results
with Panatomic X, Plus X and Tri X.
For the last 15 years I have been a devotee of PMK.
CHEERS!
BOB

According to the Kodak _Darkroom Dataguide_, D-76 (undiluted) in a
deep tank is good for 1 month. They also note with the 16 8x10 /
gallon, increase development time by 15 percent after each 4 sheets.
