Dilution B gave me a time too short to use reduced (N-1, N-2) development (Kodak says that times shorter than 5 mins may produce unsatisfactory uniformity).

I have been using Dil E (1:47), which gives me a normal dev time of about 9mins with Tri-X (TX).

The 3 1/2 min time for the new Tri-X must be a mistake, looks like the data for Dilution A.
