Actually I was thinking more along the lines of Blue and Green transmission and MG printing. Kind of to confirm or refute the idea the a different film bases or stained negatives would need a different calibration tables for MG printing.

I currently don't use staining developers because of real or imagined effects on MG printing. Would be interesting to see the magnitude of the mired shift of pyro negatives. Or, more practically, how many CCs of (yellow or whatever) the stain adds to the system.
