So it's OK to have a straight trail arm at Impact? Assuming an almost straight arm, what, if any, is the impact of having the Follow Through at such a short distance from impact?

No, you don't want to have a straight right arm before or during Impact unless you're striving for a "soft" Impact. Aim to have your Right Arm slightly bent (use some common sense here!). If it's bent too much, then maximum Clubhead Speed for that Stroke will not have been reached. If it's almost straight, you risk going into Angular Deceleration. So you want a bit of leeway.
Also, none of this matters if you don’t have your Right Forearm return to its Right Forearm Angle of Approach. That’s the by far the important thing. And it should determine the amount of bend you need. If in doubt, you want to build your pattern such that you can return to your Right Forearm Angle of Approach in the most consistent and powerful way as possible.

Interested in the location of your blue dot Tong. Is it always the bottom edge of the shoulder that TGM marks as the shoulder? Can you tell I'm no anatomy expert? Did you take into account the camera angle when you drew that TSP? I've got that clip and if I draw the line where you have it it is WELL below the shoulder at the Top. What am I missing?

I used the right shoulder joint to draw my dot. I didn't take into account the camera angle. I don't know how to do this, but if you can overlap the frame where Yoda is at the Top with the frame at Impact, it would be helpful.

I know I have left some questions unanswered because I just ain't got the time! I'm sure there are others out there who can help -- show yourselves!
