?
Well, basically I'd run out of it; loaded and shot the last of what I'd
spooled from 100' foot bulk. You can't get it that way any more.

Do you really want to be underexposing one stop?
In my view what you'd end up with is a negative under exposed one stop.
Not an ideal neg.
An ideal neg would be one which was not under nor over exposed by one stop.
As a matter of fact T max 400 in its first years out was a little slow. Many
people including me set their cameras or meters at 300 or you'd get thin
non
printable shadows.
In other words the film was really a 300 ISO film not a 400. About a half
stop slow no big deal. Not too many people were bothered by this as it was
so much higher rez than tri X.
Exposing it at higher ISO's is NOT what I'd do.
Its not known to be particularly push-able. I've not kept up with the Tmax
developer it was a terrible Phenidone developer at first way less good than
D76 1:1 which was the developer the film was invented with. I know they
improved it. - those mush Phenidone developer were never a big favorite of
hard core darkroom people.
Why not shoot Neopan 1600?
At 800 you'd be over exposing it!
Not that you'd want to do that!
Basically I'd think of film development as a function of contrast.
Not speed.
Because it is.
Mostly because pushing developers tend give such poor tonal results.
A developer which gives you normal speed or less (pyro) will give superior
results every time. Xtol. D76.
