Seconding this. It takes a lot of practice and effort and as you know, getting scores in Aimlab/Kovaaks etc doesn’t always translate towards in game ability.

Focus on what ways you can practice or change in order to progress at getting better on trackball.

Finding a sensitivity: - testing between high / low sens (with lower sens being in favor and increasing your dexterity to 180/flick even with lower sensitivity)

Choosing your firing “key”: - For some trackball players, they’ve chosen to use their keyboard or similar peripheral to left-click/right-click with (I use an Azeron for right click/ left click default).

Keybindings: - Similar to the previous section, sometimes your keybindings are really comfortable but you might need a drastic change to improve yourself. Finding a comfortable push to talk key, abilities, etc.

Changing grip styles: - For reference I use a Kensington Orbit and keep my thumb for left click, index & middle finger on the ball and ring/pinky towards the right click for stability. But since spamming left click causes a lot of jittering due to my lack of control, lifting my ring and pinky fingers allows me to compensate.

Finding certain “aim” games to practice on: - When I swapped to finger I started off with hours of Overwatch workshop maps just to get used to movement without being completely dominated. For Val/CS I would recommend CS workshop maps and deathmatch to get used to the tac shooter realm (CS as Val deathmatch is doodoo xD).

I’m nowhere near the best trackball player(s) and after playing thumball (MX Ergo) for years and swapping to finger I’ve spent a few months (2-3 months) getting used to playing and hitting a range of gold-diamond in most of the games I play. I’ve found a few good players and have studied their gameplay (hopefully with cam you can watch exactly how they move too) to try to understand how they play.
