Thanks for posting that. Now I know what you're trying to do. The club is running parallel and you're using bisecting to describe that position. You're working on swing plane so I can tell you how to check for a good swing plane with confidence. Place the camera behind your hands and point it straight down the target line. Draw a line with a swing app, I use V1 golf, from the hosel of the club and extend it to you're lower right elbow and stretch the line all the way up. That's your elbow plane and the closer you can stay on that line coming down the better. It may shallow below it during your transition which is fine, depending on your unique swing or above it if you are casting the club. So to be clear , hosel to right elbow and draw a nice straight line across those two spots from DTL. Can't tell but you may be trying to get under plane and getting too shallow. That line is your guide to good swing plane. Every swing is unique but that shaft needs to be getting near that line when the plane is coming down at some point. If you get dead on it when your hands are approaching your right hip, you're good.
