The videos fall into two categories: Person stares at camera and mumbles something incomprehensible. This is not the participatory museum experience of my dreams.
Impact and Followthrough Click on any of the hyperlinks to rapidly navigate to another section of the review: I have three different practical definitions regarding the definitional concept of the "impact zone".
First definition - general impact zone Capture images from the famous Nike commercial video of Tiger Woods' swing  Image 1 shows Tiger's clubshaft being parallel to the ground at the end of the mid-downswing.
The P system allows me to more precisely describe a golfer's position - for example, the P6.
The yellow-colored area in image 3 the composite image represents the general impact zone and it is the zone between the P6 position and the P8 position.
Second definition - impact zone Capture images from the famous Nike commercial video of Tiger Woods' swing  The impact zone starts approximately 18" before impact roughly at the P6.
Note that Part of chapter 1 of impact clubface is slightly open to the clubhead arc and target at this time point. The impact zone ends approximately 18" after impact when both arms are straight roughly at the P7. Note that the clubface is slightly closed to the clubhead arc and target at this time point.
Image 3 the composite image shows the impact zone as the red-colored area, and this is the zone where the relevant hand release actions happen. In a traditional swinger's action, the relevant hand release actions usually include the pre-impact release swivel action release of PA 3 and the initial phase of the post-impact no-roll or roll hand release action.
Between these two biomechanical actions there is a transition zone where the clubface should be square to the clubhead arc and the target, and impact must occur within this transition zone so that the clubface is square to the target at impact - if one wants to hit the ball straight at the target.
Third definition - immediate impact zone Capture images from the famous Nike commercial video of Tiger Woods' swing  Image 1 shows the clubhead approximately 6" before impact roughly at the P6. Note that the back of Tiger's FLW and clubface are both facing the target.
Image 2 shows the clubhead approximately " after impact roughly at the P7. Image 3 the composite image shows the immediate impact zone as the orange-colored area, and impact should occur within this zone - when the clubface is square to the clubhead arc and also square to the target.
This square clubface alignment will ensure a straight ball flight presuming a level strike on the sweetspot of the clubface if the clubhead path at impact is also directed at the target. I will later describe the optimum hand release action that will most likely create these ideal clubface-alignment conditions in the immediate impact zone.
To complement the text information provided in this chapter, I have also produced a 68 minute instructional video on hand release actions through the impact zone, which I have posted on you-tube.
Hand release actions through the impact zone Before I describe the optimum hand release actions through the impact zone for a swingerI would like to take a step backwards and describe the problems that a golfer needs to solve in order to hit the ball straight.
I believe that a golfer needs to control the i clubshaft, the ii clubhead and the iii clubface during the club's passage through the impact zone in order to hit the ball straight, and a beginner golfer needs to learn these three club control-issues in that sequential order.
Starting with clubshaft control.
I believe that optimum clubshaft control for a straight ball flight pattern will ensure that the clubshaft travels parallel to the surface of the impact zone's inclined plane, and that the generated clubhead arc is symmetrical to the ball-target line, so that the clubhead can be located on the ball-target line at impact or low point if the ball is placed at low point and be traveling in the direction of the target during impact.
Optimum in-to-square-to-in clubhead path for a straight ball flight The blue line represents the ball-target line and the curved red arrowed line represents the clubhead arc through the impact zone. Note the symmetry of the clubhead arc to the ball-target line.
I have discussed this issue in great depth in a number of my review papers, and I will not repeat the instructional information in this review paper.

Winston Smith, his chin nuzzled into his breast in an effort to escape the vile wind, slipped quickly through the glass doors of Victory Mansions, though not quickly enough to prevent a swirl of gritty dust from entering along with him.
