Timing of Backswing, Downswing and Backswing/Downswing Ratio
Swing tempo is calculated as the ratio of backswing / downswing. The slower the backswing compared to downswing the higher the ratio.
Swing tempo is very important to consistency. The best players in the world are also very consistent in their swing tempo. Improving the tempo can be a shortcut to better golf and is especially important for short game and distance wedges.
Usually the full swing ratio we observe for good players is in the range 2.7-3.3. But there are great players also outside this range.
The top of the backswing is identified when the hand movement is changing direction.
