Event_Labels are defined by the C3D format. Event_Labels exist only at Motion Capture frames (e.g. at Point Rate or video rate). For model based kinematic and kinetic calculations this is fine, because these signals only exist at Motion Capture frames.

For measures of timing that involve signals that are at ANALOG rate (e.g. Force Platform data) the motion capture rate (or point rate) isn't sufficient.

In Version 5 a series of metric commands were introduced to identify the time of a threshold crossing or maximum at the analog rate.

This page details the command Metric_Time_Of_Global_Maximum_From_Event that will calculate the Global Maximum timing from an Event at the analog rate.
