The 12-1-0 Pattern is a Three-Accumulator Stroke. It is not for maximum Power.
I see! I thought there is a bit more to using Accumulator #4 than merely utilising Pivot Lag. But no, so...
I have now come to a new conclusion that the 3-Barrel Hitting Pattern in 12-1-0 is inferior in terms of distance compared with the 3-Barrel Swinging Pattern in 12-2-0. Why? Geometrically, the effective Swing Radius is shortened by about four feet (or whatever the distance between your Shoulder and Feet). That is clearly a lot! Physics-wise, the Pivot Power supplying Momentum Transfer is lost. This places a lot of burden on Accumulator #1 which cannot fully compensate for all of the aforementioned factors.
Therefore, everything being roughly equal, if a competent Hitter wants to match the competitive and well-grooved 3-Barrel Swinger, he must use a 4-Barrel Stroke. Otherwise, he will start falling behind!
(PS: I do not want this thread to have anything to do with the Right Arm Swing...looking at no one in particular )
