Consistency: How you accelerate your arms in the downswing can greatly influence your ball striking.

Gears MoCap has validated the ABCs of the Golf Swing. I've identified that the acceleration rate of your arms during the transition is an absolute requirement for high-quality ball striking. Comparing two different tour players, both achieve high acceleration arm-swing rates of 77 m/s^2 in the downswing before impact. That is more than 4.25 times the rate of their hip rotation acceleration.

The idea that pelvis rotation drives the arm swing is not entirely true. Using drills - Feet Together, Flamingo Drill, and Single Arm Swings, both lead and trail can improve your swing consistency.
