02 Evidence ladder
Four kinds of number.
Most fitness products flatten every measurement into one score. Readiness does not work that way: the difference between a number you typed, a number a camera estimated and a number a person attested is the whole point.
Class 02
Device practice estimate
- Origin
- On-device camera estimation, reviewed by the participant.
- Permitted claim
- Calibrated travel or position time was observed by the device.
- Never claims
- Not form verification. It observes head travel, never elbow angle, spinal alignment or hip position.
A practice estimate is never presented as an official score, and no automation ever attests a result on its own. Class 04 is issued by a governing service, not by this product.
