Field notes
The homepage separates camera observations from inferences: solid numbers represent measured concentric speeds, while purple values represent estimated reps in reserve. Its back-squat example runs from 0.84 to 0.61 m/s across five reps, calculates 22% velocity loss, and labels the estimate medium confidence. The site describes a nine-week sample block in which load increases occur only when measured effort leaves room.
