But remember that the data on J&C Classic 200 film represents my first testing oif this film, and is not backed up by any field testing.

And there may be consistency issues. It is my understanding that both Bergger BPF and the J&C film are made at the same plant. Are the differences between the two due to some tweaking of the emulsion, or are they due to other factors such as aging, quality control, etc? Only more experience in working with the film can answer these questions.
