>>> I did figure that out.I am wondering in the data you mentioned below comparing one armed and 2 armed swings how one armed back arm compares with one armed lead arm.CAn you break it out a little more for us ? <<<

> I never took bat speed reading while working with the lead-arm. Most students have the tendency to use the un-flexing of their elbow to accelerate the bat. This resulted in disconnection. My work with the lead-arm was to teach them to keep the arm across their chest and allow rotation to bring the hand (and bat) to the contact zone.

> I was not that interested in the bat speed they developed. I was more concerned that they learned the proper role of the lead-arm with rotational transfer mechanics. The proper use of the lead-arm also became very important in correctly performing the “seven iron” (THT) drill. – Most students have the tendency to separate the lead-arm away from the chest while first learning the drill, this leads to many problems.

Terrific!!!
"The angle formed by the left arm and left shoulder forms the fourth power accumulator .. it is Pivot (body) power supplying the initial acceleration of the stroke to throw the lever assemblies toward impact by the thrust of the shoulder turn. Another major impact contribution to impact pwoer is geometric - it is the first link in theswing radius power train between the bat and feet."
