2 things Tony.....
Yes we should practice our putting more than we do....absolutely agree with that. Better putting WILL lower scores, especially close in and good lag putting.
But likewise, it is also important to hit the ball close enough to give yourself birdie chances. No point spending hours practising 50 feet putts because you're not going to hole them*, the time spent learning to hit it within 10 feet will be more productive.
*But make sure you practice lagging them close so you 2 putt
