Looks like your pinion is between 11 and 12 and your d/s is about 22.

I read 22 for drive shaft and 5 for pinion.

If it's not supposed to move and does use duct tape.

so does that mean i need to add an additional 10* shims to the existing 6* shims that are already in place? this is where i am confused. i feel as if my diff is not 11* off from the ds.

You're right. Not sure how I ended up with 11 or 12. I just set mine up last weekend but i just cut my spring perches off and welded some new ones on in the appropriate spot.

You would be better served to take your measurements on the flats of the yoke vs the case. The pinion yoke ears should be horizontal when measuring. Use that number (angle) and match it up against the drive line angle. Split the difference and you will have the number you are looking for. Not a bad idea to subtract a degree or two from the final number to allow for the torque created on acceleration.

The great uniting factor is that we are all jeepers at heart and are willing to help each other out even if its just a little. That's what the jeep wave is all about: community. The wave is the tip of the iceberg.
