One thing that is huge for both distance and accuracy, both driving and putting is following through. When you have a consistant and strong finish, you will notice some good results.
Exactly. One of the fundamentals of a sound stroke is acceleration, meaning you throw through the release, not to the release. Using this logic, your hand is actually moving faster after you release than before. A lot of folks put 100% into the throw, but only get 60% out of the throw. Using the acceleration concept, the numbers should be reversed; you should have 60% power going into the release, and 95-100% power coming out.
Glad to hear that things are working out for you though. Welcome to a lifelong addiction
