Adding Pinion Angle Shims - Tell Me If This Sounds Correct, Please

Pinion angle terms are critical to be on the same page, using the same terms. I agree with Trailbeast, and want to make things clear. If your o.d. is tipped down 5° from level, front to rear, then ideal for the pinion gear is 5° up from level. To get it to be there under load, somewhere around 2° static lower the the example 5° up, is what I would shoot for.
There is a whole raft of pinion angle talk, both here and B-bodies. A search should bring most of it up.
