Thank you Mike and Brian for the feedback via the video and continued education.
Here is my posting in question, responding to the Jeffy "couple questions" thread.
"Couple observations/conjectures...
1. In retrospect, through watching Mike Jacobs' video (which confused me a lot in the beginning) and subsequent reactions from people, I have come to realize and appreciate that J's video is more suited for those who are draggers AND have issues squaring the club through impact. In other words, it will be more beneficial to those who cannot effectively release the club because they are not capable of releasing the club over in the last millisecond IF they hold onto the wrist angle for "too long or too far". J recommended to start releasing early (like casting), which is at odds with what I think is appropriate for my kids, but then, my kids do not have the problem of holding on too long and too far. In my mind, J's video is a specific prescription for a subset of golfers with a particular problem. If one is a so called dragger and has no problem releasing the club properly as evidenced by a good ball flight, then the moves suggested in the video may not apply.
2. Jeffy's pic comparisons are telling, something I have come to accept intuitively, meaning, good players release differently. If we have to put them into 2 groups, namely, regular release vs delayed release, so be it. Perhaps for some indeed the hand low point is in front of the right thigh; for others, later into the impact zone. My speculation is that for regular folks with regular timing capabilities and physicality, it is conceivable that a prolonged dragging coupled with a super fast release is MORE DIFFICULT to achieve than a release that is timed earlier. In other words, IF I were a golf teacher and have a student who drags too far and cannot square the club, I will suggest the student to back off from the extreme hold and try to release earlier. Bottom line is that everything is relative and the source of feedback of all effort is the ball flight."
I cannot possibly fathom how the above can be even disputed. Just kidding of course.
I often disclose my golf background or more accurately, the lack of, when I feel the thin ice cracking under my feet. I think it is the right time to do so again: I don't play golf (or try to like some others). I simply don't have the time to work on my game at the ABC level and since my kids started, I felt i should pay attention to them more than to myself. I cannot demonstrate golf swings or anything golf related; everything in my head is conceptual and theoretical and not from experiences.
If Mike and Brian set out to help as many golfers as possible, my goal is to help only my 2 kids. Thus, the perspective and sense of responsibility are vastly different. If things do no apply to my kids, I figure I don't have to know. But Mike and Brian need to consider the entire landscape, width and depth wise and chronologically, in order to become effective teachers for all.
I have come to conclude on some of the above points from this angle. My perspective is certainly skewed because it is narrow for a purpose: to find swing improvements for only 2 kids.
Nonetheless, I find this video from Mike and Brian more understandable and agreeable. In fact, this video should be viewed along with Mike's original video for clarifying and complementary purposes.
I came away from this video with the following:
1. Dating back in the 30's and then in the 80's, prolonged hold has been taught and coined as revolutionary.
2. Mike demonstrated in the video of hand and club travelling essentially at the same pace, which is currently considered wrong, which runs counter to something Mike said in his original video that club and hand travel at different speeds, with the club travelling 4 times faster than the hand at some points.
3. Brian summarized that
A) there should be a predictable coupling point path
B) there should be a low point of the coupling point before impact which he termed as optimized.
C) can you have a forward lean style and have a predictable and optimized coupling point path? Yes.
