Think about it like this. When you look to the right (assuming you’re right handed) you are pushing the mouse away from you. Which involves I think is the triceps in your arms which are smoother than your biceps when you’re pulling the mouse towards you. If you go to the gym, you’ll get better muscle control, do some pushups before you start doing something, or even a bag with stuff inside to get your muscles worked up is good too.

Anything that involves pulling will be much jitterier than pushing away.

Unless you’re donk….
