that is confusing...hadn't noticed that before. The way I interpret it is "Thumb Edge" vs. "Pinky Edge", not necessarily using the edge of the thumb as the indicator for level/cocked/uncocked.

I agree Bam Bam Homer is just making sure we have the correct reference point the "Thumb Edge". If you were to take another reference point like the "Pinky Edge" the terms Level/Cocked/Uncocked wouldnt apply the same.

If you look at the left hand in picture 4-B-2 it shows a cocked position when related to the "Thumb Edge" but a level position when related to the "Pinky Edge". (For me the right hands in all of these pictures are distorted due to the camera angle just like Tongzilla's pictures).

In 4-B-1 he is defining the level position using the wristbone and the edge of the hand. Good job we have these pictures in the book because the wrist is made from 8 bones so which would you choose? I think he may mean the arm radius bone or maybe the scaphoid bone of the wrist? What do you think?
