Modern golf instruction has turned the word timing into a bad word by convincing golfers that a good golf swing does not depend on timing to be effective. This is a false assertion, however, because all golf swings rely on timing to some degree or another. Now I'll grant you that if your impact is dependent on a last second flip of the hands to square the club face that you will have a hard time being consistent. If, however, you are simply trying to time out the swinging of your arms and the turning of your body, as is the case with golfer who swing upright, then this task is fairly easy to repeat. Just ask Jack Nicklaus, Tom Watson or Annika Sorenstam if they have much trouble with their timing. Looks to me like they have done fairly well.
