Chris thanks for the correction. Good to know.

The type is integer and I moved them all to 10 sec poll rate and now they are always GOOD and not repeating values. I think root cause was quality status changing, [I saw an older post](https://forum.inductiveautomation.com/t/quality-change-cause-historian-log-tag-value/41189)

I am running 8.1.45.
