Hank Haney's Essentials of the Swing Quotes

“How much any of those factors is present in your swing is entirely dependent on the length of your backswing. Indeed, if you are like most people, you will be short of horizontal—and there is nothing wrong with that, as long as you are on plane. There is no rule that says you have to get the club all the way back to horizontal. Besides, the length of your arc is not how long your backswing is relative to horizontal; it is measured by the distance that the clubhead travels throughout the swing, so you can still have a big arc without getting all the way back to horizontal.”
