I am still trying to come to terms with the concept of LEVEL! I am aware of the Golden Rule related to TGM pics, namely that they illustrate what the captions are referencing.
So...the much heralded 9-2-1 # 2. Are Dianne's wrists in a level condition? In addition is you look at 10-5-A, B, C, D as examples are her wrists in a level condition as well? The only pic that I have noticed that shows Dianne with a good deal of # 3 Acc. angle is 10-6-E # 1 (hands only basic plane)
Like my herbed and spiced poultry amigo the mystical acc. 3 angle is starting to haunt me!
