How far is the Low Point Plane Line from the Impact Plane Line?
 

Is it the width of the ball? Half? From the center of the ball to the deepest part of the center of the divot?

d = v x t
 

The clubhead speed times the time the ball sticks to the clubface.

It is entirely based on ball location. I suppose you could think about low point in relation to the positioning of the left foot and your individual stance widths, for example.... inside foot for driver - middle of foot for long irons - outside foot for short irons....

I mean how far OUT from the Impact Plane Line? So if the ball is back from low point then the Impact Plane Line and the Low Point Plane line are PARALLEL lines . . . so what would be the distance between the two? Since we have an Inclined Plane we have an Inside-Out Impact . . . but how much OUT is there would you say?

Lets take Wedge . . . 7 iron . . . 5 iron?

If you accept the premise that if the Impact Plane Line and Low Point Plane line are one of the same when the ball is located at low point, then you have two variables to identify.

1. Ball location with respect to the Low Point
2. Angle of the Inclined Plane

Sounds simple but when a golfer located the ball back further other adjustment are made to accomodate the ball position so that the height of the ball does not have to be increased. Think about it, if you play the ball off you rear foot with a wedge and your normal divot is say 4 inches long, moving the ball back that far without any other changes would make for a very long and very deep divot.

Matt had a diagram which showed the lines rather well.

I'm just trying to figure out how much ACTUAL OUT there really is. But I think the OUT that you feel and try is probably way more than there actually is.

So could you tee a ball up and then put another tee in the ground where the lowest point of the divot is to get an estimate?

There is probably some formula that could solve the problem I would think . . .

I think its primarily to do with plane angle. Lets say your plane is at 60 degrees to the ground. For every centimetre you go down, you'll go out half a cm. Say you impact the ball (for arguments sake) with the leading edge at ground level at separation - at separation your impact point should be directly in the (horizontal) middle of the ball on the target line. And say you dig at divot 1 cm deep, then low point (for the horizontal middle of your club/horizontal sweetspot) should be 0.5cm outside the target line/horizontal middle of the ball). Of course it may look further out - by the distance from the middle of your club to the toe - because that's where the outside of you divot is.

Finally
 

I hope we get to an answer on this topic. And not simply that there's too many variables to produce an answer.

If we look at 2-C-1#1 we must be able to give a value for the offset in the impact point and offset to low point.

I think you are on it.

Putting
 

Great topic fellows. Homer basically said that all strokes
were the same. For overspin, he illustrated the impact above
the center of the ball with reverse loft. There is a big
question at weather the shaft was leaning forward or weather
he was using a putter with reverse loft. Anyway I guess this
brings up the question of, should you impact the ball above
the equator and go to the lower pont.. Some on the forum
suggest playing the ball forward of low point and impact above
low point which suggest deaccelation and less compression.
Bobby Locke suggest this method in saying that the club should
reach the ball before the hands. How about fail? After the
head of the clubhead passes the handle the the clubhead works
back to the handled causing deacceleration. Homer did suggest
impacting the ball at LOW POINT AND ABOVE THE CENTER OF THE
BALL. How can you do this and still go to the second plane
line down and in front to the first plane line? The same old
question, should you impact above the ball and then go to
to the second plane line forward and down from the first
plane line? In a conversation with Lynn, Homer said that
Lynn could move the ball back in his stance, using a bullseye
putter, but this suggest a shaft leaning forward. From the
literal words of Homer, pg 74, Transfer power, the swinger
can use A "REVERSE LOFTED" PUTTER for a precision "LOW POINT"
IMPACT - really a very accurate and simple procedure. If a
putter is on the gound a impact with reverse loft, the putter
actuall impacts the ball above center. This suggest that if
the ball was placed at low point, the second plane line could
be obtained without having to lean the putter forward providing
that the putter had reversed loft build in to in. Maybe this
discussion sould be in the putting section, but we are talking
about the low point plane line. I guess the overall question.
is what about the low point plane line for putting?
