Please don’t get me wrong!
When I read

or
https://klipper.discourse.group/t/lack-of-memory-barriers
I can hardly follow! I’m sure I get the point, but I’m no programmer!
My point was
rpi@54MHz e.g.
My stupid thought was, if I divide a high running clock (in software) I get a better value, because I make the error of the source clock smaller.
Common MCUs like STM32 have 8MHz clocks and multiply it up to 48MHz. So the error of the source clock will be multiplied.
