Eye deception is a frequent problem
Where you think you are aimed is not where you are actually aimed.
A perfect stroke with a flawed aim translates pretty much every time into a missed putt. So if you want to putt better, you have to send your ball off in the right direction.
At the very heart of putting is the ability to aim your putterface accurately at your intended target. Though this may seem a simple task, it is anything but simple. While your eyes are essential for alignment, what you see may not reflect reality when it comes to your aim.
Aiming is closely related to the distance to your target. The further away your target is, the greater the margin of error.
A small misalignment at the ball is magnified as the distance to the hole increases. One degree off true gives an alignment error of 0.21 inches per foot.
There are a number of ways to combat eye deception - the fallibility of your eyes when it comes to putting.
It is obvious (though not to everyone) that the best position for aiming accurately is from behind the ball. This is why the logo or line on the ball is so popular. It is therefore ironic and foolish if you use this technique to attempt to fine-tune your aim later when you are alongside the ball getting ready to putt.
If your head and eyes are in a poor position you will experience the problem of seeing the line pointing either left or right of your target. This adds to uncertainty and the urge to adjust your aim. If you intend to use the line then you must trust it. Better still, set up correctly so the line or logo points straight as you view it from above.
There is a saying that 'Seeing is Believing'. Unfortunately eye deception leads us astray as we believe we are aimed accurately when this is often not the case.
The Bottom Line? If You Can't Aim, You Can't Putt Successfully. It's that Simple.
