Good as P3200 is for a fast film my limited experience with it suggests to me that even at a 5x7 size print a P3200 neg doesn't match a TMax 400 neg

What's others' experience of this?

It's why you don't compare numbers from separate sources, because there are so many differing ways of defining the measurements. Note also that resolution and graininess are not that well-correlated.
