Use cases:
Velocity based training - Lift in the correct velocity range.
Power based training - Train to maximize power to increase vertical jump and explosiveness.
Olympic Lifting - Know if failed lift was technical (didn't get under the bar fast enough) or because of strength (bar did not reach adequate height to get under)
Correct form - Ensure the bar path is completely vertical, squat depth is low enough, catch is not too low during power clean, etc.
