I cannot imagine (possessing!) the nuanced internal calculations leading up to release:
on *this* ice, today, (such as my POST boot-up of nerve fibres reveals to me-sorta..)

That 'friction' thing, usually simplified in 101R as ƒ=μN is useless overall
--as μ is nothing-Like a 'constant'. Then you are adding angular momentum at release.
Next throw in everything about billiards, trig, and probably magick.

We must burn these people at the stake--before they become Bankers and make Wall Street look like Seminary Row.
