Not throwing stones; a sincere question in the hopes of gaining understanding... 
btw -I used to do this with masking tape lines spread out on the garage floor. Your way is better

I did make a few assumptions,
1, It is a trailing arm suspension with the axle fixed to the TA.
2, The operating radius of the TA pivot to the axle centerline is 51-1/4".
3, The instant center or TA pivot location was estimated (idk the actual location in reference to the axle).
4, The axle was moved to its new location (5" drop) by rotating the assembly at the TA pivot which does rotate the axle.
I realize the actual location of the pivot affects the amount of actual pinion rotation so I stayed on the conservative side in relation to the quadrant of the operating radius. Either way it illustrates how the pinion does rotate as the suspension travels. Let me know if you feel I missed anything my moto with cad drawings is "junk in junk out" if my assumptions are wrong than so are my results.
