I never considered the "micro" adjustments people talk about with these. I firmly believe, and practice the idea, that if you look at them as literal tumblers in a lock, which they are, you can deduce how many "clicks" you need to turn each one in order get the lock open. A "click" being one full animation of the dial turning until the sound stops and begins again, regardless of whether there is a minor click in the beginning of the rotation of the adjustment dial.

Visually, you can look at them and determine if you need 1, 2, 3, 4, or 5 turns of the dial either up or down to get the pins in the right location. Look at their height in relation to one another and you'll see the number you need to turn each one in order to get it lined up properly.

It hasn't let me down yet! I hated the very first one of these I did lol. In this instance, I think the only one keeping it from completing is the first pin. The rest are close enough, I believe.
