Out of curiosity, I just shot a few sheets of 8x10 in the studio, shot at 1/200th of a second with strobes. I compensated for bellows factor, and both shots are within 1/2 stop of each other. They're in the wash...I'll shoot some digi-snaps of them and post when they're dry.
Again...I would bow to your wisdom, and I wondered if I was seeing different things than you were. I have shot paper in the studio and outdoors, and regardless of the length of exposure it always seems to end up at about ISO 3.
I have not shot my Gretag color checker with my paper negs. That will be the next step for sure!
