The laws of physics are the same for all arrow flight, the curve of the trajectory always follows the same laws, just flatter with a faster bow.
The bow lets you feel the speed so you soon zone in.
The time it doesn't work so well is when the arrows don't match the bow, but even then we zone in fairly quick.
I'm only just getting back to shooting my regular bow, sure it's better than some of the others I'd shot in the meantime, but some of that was psychological, some was a niggling pull between my shoulder blades, some was it's better matched to my regular arrows.
A bow is a bow, even a modern recurve, as long as you throw away all the ironmongery they bolt to it
To use Glenn St Charles' expression, your "inner computer" soon works it out if you let it. He tells of the early days of compounds which he just couldn't shoot 'cos they fooled his inner computer... he experimented to find a lesser amount of let off that didn't mess his head and then he was ok with 'em.
With self bows, there isn't a great speed difference between bows of the same draw weight, unless one is a real dog! (Others may disagree with this)
