Another unique characteristic of the Flip Release is that it does not employ an aiming point.
All other Releases fall into the category of Hands Controlled Pivot procedures and utilize an aiming point.
For that reason, it is commonly associated with the Circle Delivery Path (10-23-E) of the hands and Shoulder Turn Throw (10-20-C). Release occurs when the pivot subsides and allows the left arm to begin overtaking the shoulder turn which is simply the release of Accumulator #4.
