The average player is said to take 2/3rds of his total shots from less than 100 feet from the hole.
With this in mind it's clear that you can't score well without putting at least adequately.
The "art" of putting, although no more easily perfected than the other parts of your game, has
certain characteristics which make it the ideal discipline with which to both start and finish
every practice session. In fact, putting can be practiced without ever leaving your house, and
you should hold every expectation that this "carpet" practice will pay dividends to your golf game.
I know dozens of top professionals who spend hundreds of hours practice putting on carpets to
either improve,or maintain, their putting stroke.
It's generally accepted that you're a bad putter only if you use more than the allotted 36 putts
per round, but better players actually use about 32 putts per round. This then should be your goal.
A goal which you should continually be monitoring and striving for.
