Power level drastically different after upgrade

We have seen this with a number of radios. (900 SMs to be exact). In this particular case, the SM was at firmware 8.2.4 with the SM reading the AP at -72dBm. We did a remote upgrade to 9.0 from the office so the radio didn’t move.
After the upgrade the power level reading was -83dBm. Has anyone else seen this? Should I be worried or just go by the Jitter and Link Test still?

Moto is trying to make the dB level reading closer to accurate, however I still don’t think they have it right.

I’d go with linktest jitter and rssi.

Ok, that’s what I was kind of thinking, as long as the link still works just go with it.
Thanks Jerry.
