How to use the Putter’s Target

Arnold Palmer in his book Arnold Palmer’s Complete Book of Putting describes two systems of putting by players, namely (1) those who view a curved path of the ball to the hole and (2) those who view stroking the ball to a target point wide of the hole. These two types could be called (1) ball track putting, and (2) target point putting. The Putter’s Target was designed for target point putting in supplying visual target points along the target line that passes through the hole (for picture see post [Putter's Target] attachment).
The basic procedure in its use is
1. Align the Target along the target line which is a line that passes through the hole and perpendicular to the ball-hole line.
2. Direct your first putt at the hole and check the appropriate speed by the distance that the ball passes beyond the target line.
3. Observe the color band of the Target which the ball passed under.
4. Choose the same color band on the high side of the target for your 2nd target point.
5. Make your 2nd putt directed at 2nd target point and hit the ball with the same speed as your 1st putt. The ball is expected to fall into the hole.
The procedure just described parallels that used by sport shooters and has been known for over a century when pistol competition was first introduced in the Modern Olympic Sports (1896):
1. Direct first shot at the bull’s eye.
2. Observe the circle that the bullet hits.
3. Observe where target point is on high side of the same circle.
4. Make 2nd shot at this target point. The 2nd shot is expected to hit the bull’s eye.
The principle common physical force that acts on the ball and bullet is gravity. Gravity causes the bullet to deviate from the shooter’s aim line and the ball to deviate from the putter’s aim line.

I don't believe this methodology to be infalliable...

It presumes the putting surface is similarly graded/inclined/sloped on both the original straight line ball to hole target line and the proposed "phantom hole" target line line.

Quite probably where you read in only a marginal break, yes, more often than not, this methodology would be "mostly" accurate.

But, on longer, more viciously breaking putts, I would suggest more often then not this methodology might well fail you.

Not to mention a putt that might break both ways on its journey to the hole...

Ooops, sorry, I just did...

Cheers
