why straight?

[gmbtempe]

Thank you again.

I need to work on my terminology. All of those impacts should have said separation.

Now that I have looked at 2-C-1 #1, #2, #2b and #3 in more detail, it is more clear than ever that the striker is moving to the right. One would certainly have to point this to the left to create a straight shot if hit before low point.

It looks like HK was pretty darn close to describing the D-plane in pictures.

It took me a minute to figure things out.

I respect your work, its always well thought out and above else on this wonderful internet.......fair.
