Archery projectile facility

An archery projectile facility comprising:

• a shaft;
• the shaft including at least one accelerometer operable to generate three-dimensional acceleration information;
• a body processor operably connected to the at least one accelerometer and executed to process the cylindrical and spherical coordinates in a multi-dimensional system to generate sampled information;
• a transmitter operably connected to the body processor to broadcast the sampled information;
• a receiver remote from the body and adapted to receive the sampled information, the receiver including a receiver processor adapted to generate output based on the sampled information, the output based on a determination of a selected coordinate;
• wherein the receiver processor is executed to generate a first datum based on the sampled information over a first time period of flight, and is executed to generate a second datum based on the sampled information over a second time period of flight, the first datum distinct from the second datum;
• and
• wherein the first datum is generated for sampled information prior to the selected point, and the second datum is generated for sampled information after the selected point.
