Unfortunately, I'm still trying to sort out what was done to change the parameters to accommodate the changes to UHJ.

For instance, the formula for Y' for the 45J setting is 0.132*jsum + 0.798*diff + ( ? 0.295*jsum + 0.032*diff) in forward preference mode, with the bracketed term being removed when the "Forward Preference" button is in the 'out' position.
