Once you are confident your putting technique includes a good follow through then you may need to concentrate more on your accuracy. This is an excellent tip to cure putting accuracy caused by too much backswing.
Improve Your Putting
I have read, for an accurate putt you need to swing your putter one-third in the backswing and two-thirds forward. This will give your stroke a smooth, positive swing motion. But to make sure you are not pulling the puuter too far back, or losing the line, place a 5p coin on the back of the putter blade. Unfortunately this putting exercise doesn’t work as well with two-ball putters.
To gauge the right distance and smoothness when pulling the putter back, the 5p coin should remain on the back of the putter, and only slip off as the the putter connects with the ball or in the follow through.
Try it, it’s not as simple as it sounds. Furthermore, I saw a real improvement in my putting when I was able to manage the length and steadiness of my backswing and follow-thorugh.
