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 :(

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.
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.
