Hawkin Sport Science Note: Best practice is to have the athlete jump immediately after the beep and flash to eliminate possible human error by the athlete.

Hawkin Sport Science Note: The area of interest on the figure above is displacement, specifically the image in the bottom right hand corner. See how the curve "drifts" up and to the right. This is integration drift, and will most likely alter your jump metrics if your perform more than one jump without saving the trial, or reset completely between trials.
Hawkin Sport Science Note: Ensure you have the best setup possible prior to collecting data for the day. Watch this 1-min video here on how to setup your plates and check the zero.
