I too will engage in the absurdity of rendering advice to Tiger.
Tiger, you don't need all that extra body movement. Slow the pivot down. Calmly "settle" on the downswing but dont let the left hip and leg move so violently. I know you can sling it a mile like that, like number eight at Augusta. but if you calmed it all down youd be leading by 10 shots and wouldnt need to.
Count one - top of back swing, two, impact, three follow through. Rythmically, till you do it the same way each time.
