Auto fine tune on 200-500

My 200-500 has been pretty good with my D500, but I felt that some images looked back-focused (and I mean very, very slightly).  Figured I'd try the procedure (as outlined by Steve Perry).  I did it for one of my Sigma lenses that was front-focusing, and it worked well in that case.

Anyway, after several runs, I got -3 a majority of the time, so that's what I settled on.  The negative value seems to back up my back-focusing suspicion.  This seems like a very minor change, so not sure how much difference it'll make, but I'll try it out in the field and see.  Worst case, if it doesn't help, I can just turn it off.

Have many of you bothered fine-tuning your 200-500?  I guess everyone's results will vary since it depends on the body and lens.
