No, the reason why the Hughes rockers lose ratio with the geometry correction kit is due to the location & angle of the Hughes adjuster screws.
Pic of T&D 1.45" 1.60 ratio on left; Hughes 1.52" 1.60 ratio on right; difference in pushrod adjuster screw locations & angles very apparent, and all this factors into how the different designs "work" when installed in different configurations w/ respect to the valve & shaft relationships.
