I actually agree with an important part of what you are saying. I am not presenting any of this as a “secret,” nor am I claiming that I invented something new or special. I learned this method from my Shifu, and I have been practicing on the wooden dummy since 1982.
Where I may differ is in how I understand the role of the dummy. I don’t see it simply as a collection of techniques or as an isolated part of the curriculum. For me, it is a training instrument through which qualities developed elsewhere in Wing Chun can be continuously practiced and integrated—structure, weight transfer, angles, coordination, tactile perception, changes of force, and the synchronization of the feet, body, and hands.
I would say that one of the main differences is the emphasis on wrist connection and continuous contact, rather than repeatedly connecting and disconnecting from the dummy arms. There is also no emphasis on hacking or slamming the dummy. The movement should remain connected and continuous through the transitions.
For me, wooden dummy practice should express broader principles found throughout traditional Chinese martial arts. The movement should not look as though frames are missing from a video—one position, a break, another position, another break. The transition between those positions is part of the training. In many ways, the transition is the training.
So these are not really “wooden dummy eureka moments.” I am trying to explain and visually document a particular method of practice that I learned and have spent many years developing through training. Whether someone considers that method useful is certainly open for technical discussion.
Of course, if someone prefers hacking and slamming into the dummy—usually making contact with the forearms, because repeatedly doing the same thing with the wrists would quickly become uncomfortable—that is a different approach. What I find interesting here is that the difference itself apparently needs to be explained. I would expect someone with substantial wooden dummy experience to recognize immediately the difference between repeatedly striking, disconnecting, and resetting, and maintaining wrist contact while smoothly transferring from one technique into another.
Perhaps that is the real “eureka moment”: the difference is in plain sight and visible to the eye, but seeing movement and understanding what is happening within that movement are not necessarily the same thing.
