I have noted that Virtuoso has posted new videos of his punch CP action and his pitch CF action.
I can see no evidence of a punch motion in his video, which simply indicates that we have different definitions/usages of the term "punch".
I only use the term "punch" to indicate a hitter's action and the term "pitch" for a swinger's action.
Starting with a swinger, who swings the LAFW from P4 to P7.3+, I think that the purpose of the RFFW is to support the LAFW at its end-backswing position and also during the power package slotting phase to P6+. THe "correct" supporting position for the RFFW at the end-backswing position is with the right forearm vertical (or near-vertical) and PP#3 under the shaft (and not behind the shaft). Between P4 and P6/6.5, the "correct" position of the RFFW is such that the right palm is parallel to the inclined plane, and under the left palm (which is the epicenter of the LAFW which must be lying on the surface of the inclined plane). To get the right palm parallel to the inclined plane between P4 and P6, the right humerus must remain neutral or externally rotate during the right arm adduction maneuver and the right elbow must lead. The position of the right elbow between P6 and P6.5 will be well in front of the right hip area if one uses a delayed release of PA#2 (late release) or alongside the right hip area if one uses a random release action. It may even be behind the right hip area if one releases PA#2 earlier (sweep release). Therefore, the position of the right elbow doesn't define a pitch elbow motion because it is defined by the purpose, and motion of the RFFW.
Here is Keegan Bradleys pitch elbow action.
Note how KB swings his LAFW down the inclined plane and he lets the clubshaft release within the plane of his LAFW. Note how the RFFW only supports the LAFW with the right palm parallel to the inclined plane between P4 and P6.5 and under the shaft, and the right palm only gets behind the shaft between P6.5 and P7 secondary to the release swivel action.
By contrast, a hitter doesn't load a LAFW and left wrist at the end-backswing position. He loads the right elbow at the end-backswing position by using a twistaway maneuver (and not a swinger's takeaway swivel action), and the right forearm should be angled well forward. Then, during the early mid-dowswning, a hitter uses the right shoulder's downplane motion to re-position the right elbow so that one can hit from a loaded right elbow at some time point during the mid-downswing. PP#3 must be
behind the shaft and not under the shaft in a hitter's punch motion, and therefore the right palm cannot be parallel to the inclined plane (as occurs in swingers). From the loaded right elbow position at ~P5.5, the hitter will
drive both PP#1 and PP#3 in a straight line thrust down the angle of approach towards his aiming point using an active right arm straightening action (active release of PA#1). That driving motion of the right forearm due to the active release of PA#1 will tend to keep the right elbow back behind the right hip area (as a reactive result of the thrust action), and the degree of forward motion of the right elbow in the later downswing mainly depends on the degree of forward motion of the right shoulder during that time period.
Here is a hitter's punch elbow motion.
I don't see any of those features of a hitter's punch elbow motion in Virtuoso's punch-CP video.
Here are capture videos from his punch-CP video.
Image 1 shows that he uses a swinger's takeaway swivel action. Image 2 shows that the RFFW is positioned near-vertically
under the LAFW and PP#3 is
under the shaft. Image 3 shows the right palm is parallel to the inclined plane, which characterizes a swinger's pitch elbow motion. Image 4 shows a CP-arm release action.
I think that Virtuoso is a swinger who uses a pitch elbow motion, and I am intellectually curious in understanding why he uses the term "punch" for this swing action.
Also, Virtuoso has a video which he labels "
super cp ala Lee Trevino, with left base line"
I don't think that he looks like Trevino - because Trevino used a CF-arm release action and not a CP-arm release action.
Here are comparison images.
Virtuoso has his foot stance well open (like Trevino) but he is using a CP-arm release action where he directs his hands inside-left of the ball-target line after impact, while Trevino directs his hands outwards away from his body using a CF-arm release action. Trevino always talked about "aiming left and swinging right".
