Meaning of various sensors in GPU-Z

Some sensors in GPU-Z don't have help tooltips, so I don't know exactly what they mean. I also have some doubts:

- Bus interface load: what does this measure exactly?
- Board power draw: what does this measure exactly and how does it differ from "PCIe slot power"?
- Power consumption (%): in my case this always displays "0". Why?
- PerfCap reason: whenever I save a log file, this shows numbers, and I'd like to know the correspondence of those numbers with the real "reasons".

Thanks in advance.
