This article made me conscious of my use of the mouse: I realize that I move it only with a ~3cm square, which allows to reach all corners of the screen by only moving my fingers, while the base of my palm stays "locked" to the desk. When using multiple screens, the mouse does some quick hops to reach them, but almost never leaves that square.

This requires configuring the mouse to have sufficient "speed". I've never had any musculoskeletal disorder, probably thanks to making such small moves with my hand and staying relaxed.

There’s people who use the mouse like this even in pro gaming. Then again thats where you see the biggest spectrum of ergonomics. Some people set the sensitivity so low they throw the mouse with the entire arm. I’ve even seen someone set the keyboard on the shoulder and wrap their left hand onto WASD like they are carrying a 2x4 like that.

I have found that my mouse usage also "evolved" to a similar efficiency. However this really requires a modern high DPI mouse, as I do intermittently use an ancient (1992) system with an equally ancient ball mouse, which can require a really massive "mileage" to do anything outside of native OS software.
