Additional info

Measured using average for 3 minutes with an Eve Energy Matter. I had to measure two KP125Ms to get a standby load on the Eve. The 0.475 represents half of the load of two KP125Ms. Otherwise no issues.

Sorry about the sloppy commit list. Realized I didn't create a separate branch for each. Let me know if you'd rather I just start over and resubmit.

No worries, I'm squashing the commits when merging. Looks good.
