[Observium] Windows Processor Numbers are Odd

I got observium working almost exactly how I want it, but I have an issue with Windows cpu numbers. The graph looks fine (I think), but the numbers are weird. The max numbers look like a percentage, but the now and Avg show odd things like 640.5m I have no idea what that means. Also, the processor is never identified properly.

I would happily change to wmi for Windows devices, but I'm not sure how that is done, or if it is stable.

Does anyone have any suggestions or experiences with wmi and observium?

Thanks!
