I should have realized that it was a delta value. Shame on me!
It appears that the Red speed is slightly high and Blue is just about right on. If that is the case, then the image should appear yellowish unless the contrast of the layers is very much off due to crossover.
You see, as a layer speeds up in a reversal film, the less density it contributes to the image or the lighter it gets. For example, to have a blue tint, you need lower red speed and green speed giving you more cyan dye and magenta dye.
Bottom line, the numbers make sense for a problem, most likely some sort of development problem, but there is not enough data in the control strip information to tell. Sorry. The high yellow Dmin does suggest underdevelopment in the First Developer.
