In one of your latest articles: Power mechanics of swinging, hitting and swing-hitting, you state to use the pitch-elbow when one is swing-hitting. But later on in the description of four-barrel-hitting, you say to use the punch-elbow. I am a bit confused, because I would think that swing-hitting is also four-barrel? Where do I think wrong?

Swing-hitting is four-barrel from a swing power perspective - as is the 4-barrel pattern of TGM hitting. However, the mechanics are very different. A swing-hitter is using right arm push-power to i) maintain the speed of release of PA#4 and ii) optimize the efficiency of release of PA#3 while still using a swinger's pattern - a swing pattern involving a takeaway swivel action and a release swivel action around the fulcrum point of a pitch elbow. A TGM hitter doesn't use a takeaway swivel action and a release swivel action. A TGM hitter uses a twistaway maneuver in the backswing to keep the clubface more closed to the clubhead arc as he loads the right elbow. Then, in the downswing, he has to unload the right elbow and use a punch elbow motion, rather than a pitch elbow motion. The punch elbow motion optimally releases PA#2/PA#3 without inducing a swivel motion, and it also alters the axis of rotation of the right forearm's paddlewheeling action thereby allowing a hitter to naturally use an AH action post-impact - because the right palm is perpendicular to the inclined plane as it reaches impact. A pitch elbow motion causes the right forearm to paddlewheel around a more vertical axis, and that causes the right forearm to pronate more as the right arm straightens in the late downswing - and that causes the right palm to be more vertical-to-the-ground as it reaches impact, which is the optimum right palm alignment for a swinger's post-impact HH action.
Thanks for the detailed explanation. I am trying the four-barrel at the moment to look for some gain in distance. From my experience it is also possible to push the right-arm after the elbow is placed in the pitch-location (when started the swinging), but it is indeed a bit strange and the ball mostly goto the left. Taking the punch-location is indeed easier, thanks

In a swing-hitter, the right arm straightening action (active release of PA#1) occurs in the late downswing - after the right elbow reaches its pitch elbow location. The active release of PA#1 requires exquisite timing to prevent a switting complication.
Image 1 shows the optimum impact alignment.
Image 2 shows the flipping result that will occur if the right arm push power is applied to PP#3 (instead of at PP#1) => ball goes left.
Image 3 shows what will happen if there is excessive push-force applied at PP#1 - it pushes the hands into impact too fast and results in too much forward shaft lean at impact => open clubface due to the incomplete release of PA#3 => push/push-sliced shots.
Sure makes it easier to see the differences in how the hinges work with the right forearm motion.
One comment on your videos and maybe this is to hard to do live but I think I would after they are finished break them into segments and put them on Youtube or something so people can quickly navigate to the video that relates to their question rather then sifting through an hour presentation. Youtube even lets you put them into categories within your channel, you could easily have an entire cataloged instruction series without to much effort. My Youtube is 15 minutes and I know it varies based on your viewership.
Great video and explanation. I was always in doubt how the right-hand should feel, but now it is cleared. I now actually feel the right-hand on the inclined plane with hitting and with swinging the right-hand hanging to the ground. Thanks.
