It seems to me that it has to do with the resolution of the A/D counts and the ability to actually fill the additional spaces in the map with slightly different values rather than greatly changing ones where the interpolation lines are nearly vertical.

All of the manual trucks have a higher resolution but it is only for a nice gradual pedal feel since there is no "absorption" of power by an unlocked torque converter clutch. Not saying that all of the MFD maps are as clean as the later manuals such as GDU3 but they make more logical sense than the automatics do.
