TMAX 400 is a very good film for both expansion and contraction. Using the 1:1:100 dilution of Pyrocat-HD, assuming a negative DR 1.55 for AZO, I have been able to get very good contraction development. The following information is based on tube processing with gentle but constant agitation at 72 degrees F.

N-3 7:00 minutes
N-2 8:30 minutes
N-1 11:30 minutes
N 16:30 minutes

For N or N + develoment I would recommend switching to to the 2:2:100 dilution for more reasobable develoment times.
