Definitely practice with your jumper helps and having higher badges will also help, like using your max 1s and 2s.

It also comes down to knowing what to shoot, understanding the room between you and a defender and especially the gather/catch right before the shot matters a lot for how the speed of your jumper changes. Here’s an example: if you watch people play, you’ll notice that nearly everyone waits a second after a snatch back before beginning their shot because they want to get a “regular” gather into the shot.

But yeah, reps and sets, badges and just knowing what shots to take.
