I am aware that the key points are the PP#3 (and not the hands) and the sweetspot plane (and not the clubshaft plane). However, the angular difference and point location difference is so small that using the hands/clubshaft as a surrogate visual marker is not far off. I, therefore, find your theoretical objections somewhat invalid. You are free to draw the sweetspot plane on my images, and then demonstrate the relevant differences. I will be very surprised to find that it makes any difference to my contention that "being on plane" needs to factor-in the amount of hand dropping per unit time relative to the amount of left arm rotation per unit time, and that the entire concept of "being on plane" is an arbitrary construct.

Regarding your idea of practicing "feelings" as a replacement for accurate visual examination of "real life" swings (despite the small problem of parallax error) is an even greater mistake from my perspective - in terms of understanding the concept of "being on plane" instead of the concept of "feeling on plane".

Jeff, you won't "get it" until you feel it...attach your keyboard to a shaft and start swinging instead of typing...

I agree that even with parallax some of those guys are starting down on no specific plane...not TGM plane nor Haney....they usually are on plane during release though impact.

But it really is about sweetspot feel. Homer wrote in a generation before Video cameras were readily available for golf teaching...you just don't need them to make his stuff work.

When you do you swinging with your weighted keyboard...aiming to release on a straight plane line....try and make an intentional off plane release AND then still be on plane for impact region....really hard to do...you will feel the biomechanical inefficiency...then you don't need to draw lines.
