Since the bending of the right elbow, according to TT, causes cocking of the left wrist , a larger bending of the elbow would cock the left wrist even more, thereby increasing the potential power in the downswing. However, does the decreased width with a right elbow bend larger than 90 degrees in the backstroke and the longer way(time) to a straight right arm , in reality decrease the power?

According to Homer Kelley the bending of the right elbow cocks the left wrist, this is correct but a larger bending adds nothing. It breaks down structure. The wrist cock angle is not extreme, just a few inches from Level to Cocked. No over bending of the right elbow is going to increaase that. This is more of a Hitter's procedure- muscle bend and cock. A swinger's right elbow still bends and cocks the LW but with more momentum than simply muscle action.

It is the turning power of the pivot, the gyro crank of the right shoulder thrust that allows CF to uncock the left wrist that supplies power- not the wrist angle. (Swinger)
