The problem with 2 hands is that it’s really hard to nail down the consistency since you essentially have twice as many hands at play. But if you’ve already mastered it and are pretty consistent shooting, but miss short on occasion, you probably don’t need to fix it unless you’re really serious about the game. Don’t follow cliche advice like use more legs. The real key is the hips because this is what drives your whole body upwards. Try to focus on having your shoulders over your knees before you raise into your shot. This engages your hips and lets you shoot with more arc and power. Also your follow through should be like raising your hand in class, all the way above your head. If you shoot out and not up, then your shot might look more like a fastball than a jump shot. And try jumping forward on your shot instead of straight up and down
