Settings

Sample rate and analysis options.

Sample rate (Hz) iSamples per second. Auto-detected from file if a time column is present. Used to compute acceleration.

Time block size iDuration of each bin in the Time Block chart. Smaller bins show more detail; larger bins smooth the profile.

Velocity units iUnit of your velocity column. Choose km/h if your GPS/radar export is in km/h (common for Catapult/StatSports). All metrics are reported in m/s, with km/h shown where relevant.

Apply 3-point smoothing to acceleration

Reduces noise-driven spikes in the acceleration trace.
