While I have had issues with ?all in the past (neutral), I'd avoid -all
(hard fail) if you can. Hard fail can mess up mail forwarders if
subscribers use them on their end.
Instead, I'd suggest using ~all (softfail), which most mail providers seem
to be OK with.

Mails coming through fine here. A couple of points:
"?all" means anything else is neutral. I think you want "-all".
It's my understanding that some spam-filters view other than "-all" as if
the rest doesn't really matter.
I don't see an SPF record for amprgw.ucsd.edu. If that is the machine
actually sending the mail, then I think you want that. See RFC-7208
section
2.3.
