Abstract: An improvement for a practice facility that simulates a sport playing environment, wherein the facility has a projectile striking region and a target region for the projectile. The improvement is a computerized feedback system that includes an input device for receiving participant credentials sufficient to activate the computerized feedback system and an output device for displaying perceptible output to a participant. A target array including at least one target is removably mounted in the target region and operative, when stimulated by the projectile, to produce at least one feedback signal. A data processing device is included that is adapted to receive each feedback signal produced by the target array, process selected feedback signals according to rules for the sport in order to generate processed data, and selectively transmit the processed data to the output device.
