Your jump shot, measured to the degree.

A settled moment before the dip. Great shooters look identical before every shot - that's the routine doing its job.

The dip loads your legs - elite shooters dip on almost every shot, and power comes from here, not the arms. The window is wide on purpose: across seven published proficiency splits the deepest knee bend runs 94-122 degrees, and the studies disagree about where inside that the better shooters sit - one has them deeper, one shallower, four find no difference, and the only professionals ever measured bend the LEAST of anyone at the free-throw line. So this scores whether you loaded at all, not how well you loaded. Nearly straight legs are the fault it can see.

How far your hips sink in the load. Too shallow and the arms have to muscle the shot; too deep and the rhythm dies.

The deepest bend your shooting elbow reaches between the dip and the release - and it is bent far tighter than the coaching cliche. Every study that measured a deepest bend puts skilled shooters at 50-66 degrees; nobody has ever measured a group at the 'classic L' of 90. An arm already half-straight here skips the power stage and the shot becomes a shot-put.

The launch angle of your forearm at release - a proxy for arc. Around 50 degrees sends the ball on the high, soft flight that rims forgive.

The elbow finishes almost straight - the ball leaves off a full extension and wrist snap, not a push. Read it as a yes-or-no check rather than a grade: published shooters of every level finish at 152-161 degrees, proficient and not alike, so the fault this can see is the bent, quitting arm below about 145.

Feet about shoulder width, shooting-side foot slightly forward. Your base decides whether the rest of the shot repeats.

How far your elbow sits out to the side of your wrist through the rise, averaged over the whole rise and measured in torso-lengths. A flared elbow sprays misses left and right. Only scored on a clip filmed FACING you - from the side, the elbow flares straight toward or away from the lens and no single camera can see it. The bands come from arm geometry rather than a calibration set, so read them as approximate: the segment this measures across is the forearm, elbow to wrist, which runs about half a torso-length - putting 0.12 near 14 degrees of forearm tilt and 0.32 near 39.
