Hearing things the easy part. The finer you split the hair, the harder it is to actually translate that to a tuning action, with a piano. There are no fine-grained worm gears in the tuning pegs. The pegs are just metal sticks stuck into a hole, prevented from rotating (going flat) by static friction. You cannot adjust them smoothly; when you turn them with the tuning wrench (properly called a "tuning hammer"!) you must overcome static friction to make them move. At that point, they will jump. If you're looking to make a very fine adjustment, it will be almost certainly overshot. So you must do something like jump to a sharper pitch, and from there try to relax it by jumping down to the target pitch. (And that also results in better tuning stability: lower likelihood it will slip.) If the target is very narrowly defined, this can take multiple attempts. The piano has 88 keys, the bulk of which have three strings: have fun!

... but why? sure gears - like on guitars - would be probably too big and wouldn't fit[0], right? (and/or too expensive) but they could put the knobs on the top of the peg ... the gear could be inside, and as it is rotated it could push out small cams or "break pads" to make a wedge[1], same friction would make sure the pin stays in place and does not rotate, but no need for the hammering. of course probably because of acoustic this or that having solid pins is "much" better?
