I see, ewolf, but I do not see an exaggerated bend in bow-arm and the question remains: "How bent is bent?" I believe that Art P has somewhat defined it (degree of bend) when he said "…soft bend," as has Ragsdale.
There are shooters that do not understand that the bend that is recommended is the natural bending (cracking) that occurs when you rotate your elbow outboard and do not over-extend your bow arm. However, not all do. Some shooters believe you exaggerate the bend to get their bow-arm and clothing away from the oncoming string, compensate for short draw-length, compensate for over-bowed, etc; and the method is correct form. That is "adaptation."
