This is just incorrect. Precision is about consistency; a jump that varies in height every single time it's pressed is by definition imprecise. If the nail length was defined by the amount of time the button is held as well this would also suck, but hey, it's entirely consistent and predefined because that works. It's almost like platformers figured this out literal decades ago. Asking players to remember to hold the jump button for specific amounts of time at every single hard fight that has a million other things going on and thus buttons to press is not hard, just an annoyance.
But I can tell by your reply that you're a Cherry drone so this is my only answer to you. May they pay you someday, my friend.
