Well - what do you know!
Maybe not a misprint after all. Is properly better than practically since they changed it in the 7. edition?

I already know that the Ball should leave at right angles unless I want otherwise and I know how to make it happen. So, it doesn't matter to me either way. But I do like the word "Proper". It is the "Proper way".........to leave at Right Angles...

AirAir, I think you should understand something. Hinging is the easy part. Not disturbing the Sweetspot Orbit is the Hard Thing. That's what TGM will teach you. And you'll learn that you need a "Flat Left Wrist" to learn how not to disturb the Orbit. If you can get a Flat Left Wrist through Impact, everything else will almost fall in place.

The Clubhead, with a Driver, and the Ball Played back 1 inch behind Low-Point, will travel downwards 1/50th of an inch and outward even less before ball separation. That's how critical it is. 1/50th of an inch. That's the difference between full compression or not. Even with a Putt. You need Hinge Action even with a Putt to gain compression.

It's technique that allows the perfect Orbit of the Sweetspot.
