Get_performance_data (cpu_info) understanding

Appium supports getting performance data by .get_performance_data(appPackageName, datatype, timeout) method.

I use this method to get cpuInfo and resulting output is:
[[‘user’, ‘kernel’], [‘34’, ‘5.9’]]

I am not sure what does values mean - are they percentage values of user and kernel cpu shares of my app?

Please do not send me to android adb dumpsys cpufino docs, just let me know what do these values mean
