I did that with P3200 once. Shot it at 400. And after studying the charts
(no listing for shooting it at 400) and extrapolating, I figured it would
be about the same time as TMax 400. So I threw it in with a 400 run. Turned
out amazingly good. It created a major reduction in contrast. I was able to
photograph a class (remember this was accidental) with shadow detail and
yet outside the building across the street was a white house in broad
daylight with snow on the ground that wasn't blown out at expected. (It did
take some printing skill for sure, but it was much better than I would have
expected!).
But that's not saying I'd just have to reduce development to do it at 100
right. There is a point where overexposure to the grains that exist in the
film (bigger for faster film) will cause major problems, such as blocking
up of highlights and likely an increase in grain that would be unacceptable.
