I completely agree somehow since the time is not even constant and depends on
the PLL settings just done before.

I suggest the following:

Removing the "* 3" fancy thingy in the function's loop, calling the
function with 3000 instead of 1000, changing comment to "needed on some
Beaglebone Black for warm start after reset".

That would be as simple as possible.

Konsti
