Response to B&W film evaluations - TMax 100

the developing times for Delta 100, per spec, are a minute longer than for TMax 100. and so, I was surprised to have overdeveloped TMax and underdevelop Delta 100, and find much greater densities with the Ilford film. nothing scientific at this stage. I picked up John Sexton's book and noticed he rates TMax 100 at ISO64, which is more in-line with what I have observed.
