Distributor specifications

I was building a couple of distributors today, checked specifications and wondered why so different. I only have a Studebaker Shop Manual, so if anyone has a Packard Shop Manual to confirm are these the same in there:

Stude Shop Manual - Autolite distributor 32 degrees centrifugal, 22 degrees vacuum, 5 degrees BTDC timing. The 5 initial plus 32 centrifugal would be 37 total.

A.E.A. Tune up system chart - Delco distributor 26 degrees centrifugal, 17.5 degrees vacuum, 10 degrees BTDC timing. The 10 initial plus 26 centrifugal would be 36 total.

Main question is does the Packard Shop Manual say 5 degrees initial for Autolite and 10 degrees initial for Delco?

thnx, jack vines
