Good question!
Is over-acceleration the same thing as just being to quick from the top?
No.
"Over-Acceleration" is term that means that the arms hands and club—the "Power Package"—have moved INDEPNDENTLY of the Pivot TO AND THROUGH IMPACT.
Also, does anyone have any drills for perfecting one's tempo? Thanks.
The MANZELLA SEVEN-BALL DRILL!
Place seven balls about 4 inches apart, perpendicular to the target line.
Use a mid-iron. Use your "normal" distance for that club as the base distance for this drill.
For example, my 7-iron distance is 160.
Hit the following seven shots in this order.
1. Hit a 25% distance shot (in my example, 40 yards), using just enough swing for 25% distance (my example, 40 yards). Normal "ummph."
2. Hit a 50% distance shot (in my example, 80 yards), using just enough swing for 50% distance (my example, 80 yards). Normal "ummph."
3. Hit a 75% distance shot (in my example, 120 yards), using just enough swing for 75% distance (my example, 120 yards). Normal "ummph."
4. Hit a Full shot (in my example, 160 yards), using your normal LENGTH full swing. Normal "ummph."
5. Hit a 75% distance shot (in my example, 120 yards), using your normal LENGTH full swing. DON'T EASE UP! Make the whole FULL SWING 75% speed.
6. Hit a 50% distance shot (in my example, 80 yards), using your normal LENGTH full swing. DON'T EASE UP! Make the whole FULL SWING 50% speed.
7. Hit a 25% distance shot (in my example, 40 yards), using your normal LENGTH full swing. DON'T EASE UP! Make the whole FULL SWING 25% speed.
You'll have 7 shots for every club, and you'll have a great FEEL for tempo.
