When I’m using a trackball the end of my movement is actually the most precise, ime. The way I use the trackball is to ‘launch’ it roughly in the direction that I want, and then when the cursor is close enough to the target, you ‘stop’ the trackball and precisely move it to the destination. It’s not a single movement it’s like a flick and then a halt and precise movement.
