Kyle he shot two 1600 rolls at 3200... that's cool and they'll be OK. It's
the roll of Provia 100 that he also rated at 3200 and that's screwed! It's
underexposed by 5 stops!!!!  The film has a rating of ASA 100. It was
underexposed by 5 times at 3200!!! The chances of anything being there with
any kind of super soup is unlikely, certainly anything useable.

If it were a roll of ASA 3200 and exposed at 100 that would be "OVEREXPOSED
by 5 stops!" And pulled process might, although unlikely,  show something.
But the highlights would be so blown out even with pulled processing it
wouldn't produce a useable image, certainly nothing to match the other two
rolls shot and souped properly.
