ODD time intervals on main WD Page [Resolved]

Since going to Sierra I noticed over night the time intervals at the bottom right are weird - spaced close together then far etc

See screen shot

I checked the app and the “prevent app nap” was not checked. Could that have been it?

Looks like it was the AppNap… Since changing that it seems to be doing much better
