Can someone verify if my pinion angle diagram is correct?

Trax, we use a different method of measuring pinion angle. We take measurement at the rearend or torque arm bracket if it has one, then at the rear of the drive shaft. We have a video on our site about the proper way to do this. I'll post a link to it, if you have any questions please give us a call. Our tech dept. is open MON-FRI 8:30AM-6:00PM EST.

I don't like it,'our' pinion angle is only that of the relationship between the driveshaft and pinion because aftermarket torque arms generally have some degree of adjustability.The angle at the transmission output shaft and the driveshaft is 'nonadjustable'?,but is affected by changes of the pinion angle at the pinion.
We strive for -1 1/2 to -2 degrees difference at the rearend with the pinion pointing downward as compared to if perfect alignment existed at +-0 degrees.

-4 - (-2) = -2
The tailshaft is pointing down to the right and the pinion is pointing up to the left--so they both have a negative slope. The pinion is 2 degrees less negative than the output shaft of the transmission.
