What do the videos you have seen tell you about where the racket should face, and where it should be? (you can include timeframes, still images). Re your racket head dropping, see post #109, (Page 6 of the thread)., where we managed to get Cheung to provide a timeframe and a diagram of what he meant! That is very useful. (put aside some technicalities re that diagram that have been mentioned, and not to you, about forearm and racket shaft). As to how to get there(that diagram), you could think about some of the anatomical changes you could make to get the racket shaft or the forearm more upright, then ask if they are correct.. You could think about, what happens when you raise the elbow, does the elbow also come out a bit, and does that change the orientation of the forearm. Does externally rotating the upper arm make a difference. You could try some of those anatomical changes to get a better understanding of how they affect where the racket is, and see how it looks You could even do a video saying "is the racket preparation like this? Is it like this.." and see what is advised. And hopefully people can point to timeframes showing you exactly what they are talking about.
