Yes Jason. Apparently they did this at Maine Photographic Workshops in some courses. I picked up their method from workshop handbooks they sold and I used it in that fashion for many years to the exclusion of all other developers.
My development time is 6 minutes at 68F for everything though dilutions may run from 1+9 to 1+39. Normal with TMAX 400 happens around 1+24 for me.
The stock solution is mixed 1+9 and extra water gives the working dilutions. I used to break them down into additions of 5 parts (i.e., 1+9, 1+14, 1+19, 1+24, 1+29, etc.)
Works for me and I enjoy the shorter times and increased flexibility with that developer.
