Tell you what. If you develop that roll of TMax normally, while shot at 25, you're going to have a very difficult time in the darkroom printing it. And I can see how shooting a roll of FP4+/Plus-X at 32, Delta 100/Acros/Foma100/Efke100 at 25 would give equal amounts of trouble with a tone scale slid way up the film curve and the highlights at risk of completely blocking up, so that the enlarger can't shine through them (let alone a scanner).
For what it's worth, I get the 'best' tonality with TMax 100 shot at 200. For normal contrast. For high contrast it's 100. And for low contrast 400.
The real recommendation that needs to be made is to test the normal speed of the film by shooting in normal contrast and exposing at lots of different exposure indexes, develop normally and see where the shadow contrast is what you would like it to be. And that will be different for everyone.
