F9P output in AOG

I have a F9P and I’m getting a very solid RTK fix. In the center of the top of the screen the bottom figure is AOG HZ rate???

I have 8 HZ set in AOG and on the F9P.

On top of this rate is Actual info for the F9P???

The top numbers will jump around from 8, 9, 10, 11, 12. Is this normal??

Those numbers are how long it takes your computer to process the AoG data at each GPS input.
