Another Pinion angle question

[gtbrain]

Yep, I've read a pile of posts on setting pinion angle and I'm still not sure if I'm going at it right.

I have 0 degrees at the transmission yoke.
After tightening my carrier bearing, I have 0 degrees at the end of my first driveline.
At the rearend, i am at -1 degree. My pinion is pointing down slightly.

Is this acceptable?

Thanks in advance for any input.
