That said, I do have to question you apparent use of AF-C for this
stationary subject given my experience.

I was using back-button focussing.

Most of my experience with AF-C is with a big heavy setup (200-400mm
f/4 + TC-14) which is tough to hold steady for extended periods. Maybe
this has jaded me, but I always "try" to switch back to AF-s for fixed
subjects. I just seem to get better results that way. YMMV.

What camera?

D200/D300/D71000 and now 6k shots into D500.
AF-C priority set to focus, not release.
