A stroke analysis is a comparison between your stroke and the pendulum stroke recommended by most professional pool players and adopted by the PBIA and ACS as the standard stroke. The process uses a video of the student student shooting pool. The video is taken at different positions and angles - back, front, side, elevated and overhead views are captured. Slides are made from this video at the set pause and finish positions of the stroke. Deviations from the standard stroke can be identified and mapped. Deviations that are highly likely to introduce an error and result in a missed shot are identified with recommendations to correct.
