Since the potentiometers are analog, they are advertising it as “theoretically infinite”. I stumbled upon these endless pots by chance after looking at options to do something like this for years. I have experimented with optical mice sensors, thought about hall effect sensors and IMUs. These pots do everything I wished for. Like I said in another comment, I think it's at a point where timing/MIDI bandwidth is factoring in more than the resolution. And yeah, the reason why I never picked up a higher resolution encoder was just the price.
