AAAAAAAAAAAAAAA! I scream every time someone asks about % which is about once a month.

I asked about this last month, so you were due for another.
Anyway, D316 is passing more tests:

• It can be stored in the refrigerator with no precipitation.
• It can be stored in the freezer with no precipitation. When frozen, I believe it will last years.

I'm starting to test various films with D316, and FP4+ did fine. Its density-curve matches XTOL, shown below.

The curves are close enough. I think using a dev-time of 16.25 minutes (instead of 15.7) would be an excellent match. But I ran out of HP4+, so it's time to give Freestyle some business. BTW, you'll notice all my graphs have a small inflection at X=1.5. That's because the illumination of my light-table isn't uniform, and 1.5 is the transition between the two rows on the Stouffer chart. For comparisons with frames shot the same way but developed in XTOL, it makes no difference.
