Makes sense. ntpheat was designed on a RasPi 3. So not a problem.
Apologies - my units are RPI 3B+. The 3B+ only supports those two
frequencies - no scaling between them- and that's the source of the
added 'noise'.
That is a limitation of your setup, not of the Raspberry Pi or the
kernel it runs. My RasPi's have no problem with intermediate
CPU frequencies.
I have also heard of people using the GPU to control the PCB temp.
that does not affect the CPU latency.
