Right Leg Loading and Weight transfer

I shot this video today to demonstrate the role of the right leg in loading pressure and it's role in pushing weight from right foot toward the target through the strike of the shot.
The idea that weight should immediately be planted into the left leg at transition as some instruction indicates is not an optimal action. The notion that the swing is governed by a powering from the ground up that starts with planting the left foot then straightening the left leg is false.
In this clip hitting a persimmon driver off the ground, my left foot does not even contact the ground until PV5 or right near finish of the swing. This ball was absolutely nailed hard. The ground up pressure comes primarily from the right leg, ankle, foot and knee.
I shot this still wearing a street shoe and you can see the right foot almost slip out on me due the forces exerted there. Next time I will lace up a proper shoe with steel spikes and really get on it.
