You're Swiveling. Hinge Actions do not produce those Ball Flight errors.

Grab a Bucket. Hold the handle in your Right Hand. Wrist facing up and put a red dot on your wrist. Red dot faces up. With your right arm only, Release slowly from right to left. The top of the bucket should remain level during release and impact.

If you're swiveling, then the top of the bucket won't be level.

Dammit another great post!
