I've never used CPUFriend before, but now I need to learn how to use it given I have an 8th Gen CPU.
Will take a look when I'm back from travels next week. In the meantime stay tuned
I've been able to build a CPUfriend kext for my 8550U and have idle CPU average 0.63-0.72 GHz (of course the spike at the end of the run is the load from taking the screenshot).
P-State ratio * 100 = Frequency in MHz
