Abstract: An archery bow facility for launching an arrow includes a flexible bow and a bow string connected to the bow. A sensor connected to the bow is operable to generate a datastream based on a condition of the bow. A processor and display in communication with the sensor is operable to receive the datastream and to determine a first bow position at a moment of initiation of release when the bowstring is released by a user. The processor, based on the datastream, then operates to determine a second bow position at a moment of conclusion of release when the arrow departs the bowstring. The processor may operate in conjunction with the display to communicate to a user information about the difference between the first and second positions. The first and second position may be first and second angular orientations, and the sensor is preferably a multi-axis accelerometer.
