CPU load API values meaning

[cincura.net 13]

The REST API documentation says the values in `cpuLoad` are percent in user/system/idle. But when I check the API, the values do not look like a percent at all.

What is the unit? Can somebody shed some light on it?

Some calculation require to get actual CPU load in %

These calculations look strange... isn't nice a part of user? It's usually 0 on the HC3 but anyway... and doesn't the percentage calculation always return 100?  sorry, didn't see the 'p' prefix of idle the variables.. but should nice be included?
