I find two sentences in this report really bizarre:

Why would a small change in frequency have much effect on the power
used? Surely reducing the voltage would have an effect but not
reducing the frequency (except maybe marginally).

Umm, why should the supply frequency affect a crystal oscillator?
I think they mean non-quartz clocks.
