Since the camera was rebuilt, were you sure of the shutter speeds?

Reasonably, yes. It's a Pax M4, which has a really simple leaf shutter.
Hard for it not to be (at least somewhat) accurate. I can test it with
my shutter speed tester, but the exposures seem to correspond well. I'll
probably do that the next couple of days.

Ack! Posted that too soon.

Turns out the shutter speeds for that camera (the Pax I shot the roll of
film with) plus another one were pretty far off--like almost twice as
slow as they should be at most speeds.

Still, that means the exposure would have been off by 1 stop, not a huge
amount, so my original premise that the developer I used is still
practically full strength is correct. It's just that the over-density
wasn't helped by the slow shutter.
