Do u have the book? What's absurd is u telling to pull up the hands right before impact

I owned the book before you even existed.

I didn't say that it should be done as a deliberate action. It happens because impact hands location for a good swing is past low point of the hands, which are being pulled up and in by the left shoulder.

So, let's look at the Impact picture 9-3-10 on pg. 131 in the book(6th ed). Look at the white hand path and look at where the hands are at Impact - they are on the upward arc. They have passed their low point and are moving upward at Impact.
