Comments:   The information outlined here will be for Kodak's T-Max 400 in the 4x5 film size. I develop most of my film in BTZS tubes.

Comments:  These times are for roll films in small tanks, optimized for a diffusion enlarger.  For PMK and PMK+, agitation is for first 30 seconds, then 5 seconds each 30 seconds thereafter.  For all others, agitation is for first 30 seconds, then 10 seconds each minute thereafter.

Comments: I use HC-110 diluted out to 1:11 from the stock solution. This is instead of something normal like Dil. B at 1:7. For sheets of TMY 400 I expose at 200.  I use old hard rubber tanks and hangers, with first 30 second agitation, then 5 seconds at each minute.  I suspect my plus/minus changes are not real accurate, but I have a good feeling for how much change that is in practical situations.  I use the same developer for the film in 120, but to keep measuring simpler I use it at 1:10 and cut :30 seconds off the time.
