I would test before making any changes. Your results may vary from those stated in the literature. Your results are dependent on agitation technique and temperature; so I would rate the film as normal and see how the film turns out.

FWIW, my practice in starting off with a new film is to take a roll with bracketed exposures of each shot, 1/2 and 1 stop over and under, and one at the indicated exposure. For pyro (PMK Pyro from Photographers' Formulary) I have found that the 100 and 400 Delta films print better when overexposed 1/2 to 1 stop - I use mostly the 400, and shoot it at 200 or 250. I've also found that 35mm negatives look a little better developed 1 minute less than the time indicated in the instructions that accompany the developer, while I use the full recommended time for rolls.

Of course, your mileage may vary. But if your tests indicate better results at a little more exposure and a little less development than standard, you won't be the first to so find.

I've gotten some superb results from pyro. Enjoy.

I rate Delta 100 at 50 for development in PMK. The advantage for the long-scale subjects here in Texas is that I get good shadow detail due to the full exposure, but because much of the density comes from stain, I can still see through the highlight values, which means I can still print detail in them. Kodak Elite Grade 1 is perfect for these long-scale negatives.
