If your discus keeps drifting right and landing on the edge of the sector or out of it, you are losing distance and legal throws to a timing problem. For a right-handed thrower, a discus that goes right almost always means you opened up too early and released late, so the throw came off the wrong part of your turn. It is a common, fixable fault. Here is what is happening and how to send it down the middle.
If your upper body unwinds before your hips and legs have done their work, you spend the throw facing the wrong direction and the discus releases off to the side. The throw should stay wound, the chest closed, until the lower body has driven through. Early shoulders send it right.
A discus released a fraction late, after your arm has already swung past the center of the sector, naturally flies right. The release should come as your hand crosses the middle of the sector, not after. Late timing here is usually the downstream effect of opening early.
Yanking the discus in toward your body and across your chest, instead of letting it ride out on a long, wide arc, drags the release off line. A long arm and a wide orbit keep the release pointed where you are throwing. A tight, muscled pull sends it right.
Whether the discus leaves on line is decided by the orientation of your shoulders and arm at release, which is a single frame from behind. Film the throw, the AI shows your release timing relative to the sector and whether your shoulders opened early, so you can fix the cause instead of aiming left to compensate.

A throw released on time, as the hand crosses the middle, flies down the center of the sector. Opening the shoulders early pushes the release late and sends the discus toward the right line.
