 From what nia@ tells me (and this is also in the guide: section 11.1.4.),
you shouldn't need estd at all:

     Many modern hardware supports an "automatic adjustment" frequency,
     usually this will be a reported frequency that ends in 1. On systems
     without this functionality, sysutils/estd can be installed from
     pkgsrc to perform automatic adjustment depending on load in software,
     although it will be less efficient than hardware scaling.

Ah thats good info that I DIDN'T know. Sadly all my BSD hardware is from the generations before the full 'auto adjust' was added. I think that's intel core gen 6 and mine is gen5. So in my case I really do need estd :(

On older hardware the xxx1 frequency in my hardware enables the turbo boost clocks which overclocks cores beyond the max. 4GHz to 4.4GHz in my case I think. I didn't realise that had been repurposed in newer cores to be (let the CPU adjust across all speeds) I sort of assumed that would be reported differently.

I do know that estd makes a significant different to temperature and power consumption when my system is idle vs when its busy.
