Cleeve;
I noted the requirement of -4 degrees but I have been bitten too many times
by just meeting the spec. doing a bunch of work on something and coming
back later and not meeting the requirement later. I wholely expect
something to change after bonding the top on the whole mess and will not
enjoy crawling back there when the two halfs are together. So I'm
shooting for the 5 or better to ensure 4 later on.

broadened in the Annex E page 2, Final Inspection Checklist, where they
specify +12 to 13 degrees and - 4 to 5 degrees.
