What if you want to draw the ball? You rotate your plane line, but the target line is still the same. The intended line of flight now is for the ball to start to the right of the target.
Been noticing lately the use of some terms that make me wonder if we are talking about the same thing....
I originally voted for - sometimes the same - sometimes not.... it seemed to be instinct but the question was bugging my mind for a while...
But ive changed my mind after thinking about this a little - the plane line is the base of the inclined plane where it goes into the ground (as depicted in 1-L - The machine concept). The flight line is parallel and slightly in front of the plane line. The clubshaft rests on the inclined plane which is slightly in from the sweetspot ... I think he even says they are parallel in one of the observations in 1-L - if they are parallel they are not the same....
The ball always starts from that parallel to the plane line location - so they can NEVER EVER be the same.... if you draw a line wiith two points on either end - one point is always OFF the plane line....no matter what the intended line or type of flight may be (even if the ball lands exactly on the plane line when it drops) - means they are not the same
Infact if you truely want to stroke having the plane line and flight line the same - welcome to the world of the shanks
Per 3-F-7-A, you always Swing along the Plane Line but not always along the Flight Line.
In regards to the flight line 'Along' yes - 'On' no....IMO and I strongly believe homers too. They are still parallel - they both are still different... everytime !
The answer to this is found in the definition of your terms- I believe the direction this thread should go, is for people to begin to post definitions for the above concepts. Intended line of flight?- Initial line of flight? i.e. the RF vector? Target line- the initial line of flight?- that point in the distance where you're going to start your ball flight?, or a line from your ball to the eventual target? Probably the best definition will be the one that encompasses both draws, fades and straight shots and not just straight shots. And that is why I think that Homer Kelley saw to define the initial line of flight to be the same as the target line- the target line was also the initial line of flight, regardless of where the ball eventually finished. (10-5-D photo, 10-5-E photo) Like I have said before - I believe the Golfing Machine's concept of "Target Line" is very different than the common golfing community's concept of "Target Line" i.e. that line from the ball to the flagstick.
