We have worked with top-level instructor-examiners from PSIA (The Professional Ski Instructors of America), CSIA (Canadian Ski Instructors Association) and other federations to create metrics that assess your technique for a broad range of turn types.
The metrics measured by the 36 sensors in the Carv inserts and group your technique into four fundamental skills, agreed upon by the major skiing federations.
These are Balance, Edging, Rotary and Pressure.
Your ability in each of these skills are defined by a range of specific metrics. Just like IQ scoring, these component parts are used to create a Ski:IQ™, which is a quantified estimate of your ski technique calculated in the same way for every Carv skier.
Carv's sensors calculate your technique based on a wide range of factors, developed with ski instructors and data scientists.
Edging - Ski roll (angle, smoothness, early vs late edging)
Pressure (outside:inside pressure, rate of change, timing)
Balance (dynamic balance in the turn, forward stance, foot roll)
Rotation (yaw rate, yaw symmetry, yaw smoothness, yaw/edge relationship)
Symmetry (are you the metrics above the same for left/right turns)
Similarity (are you moving your left and right ski in unison)
Your data is presented as a Ski:IQ score with scores for each of the components of great skiing (balance, edging, pressure, rotation).
Every season we evaluate our metrics to make sure we are using our sensors and our growing data system (36 million turns and counting) to accurately describe what great skiing looks like.

Metrics and coaching
Your metrics are used to define what kind of coaching you will receive. Carv works by giving you advice based on the metrics that are consistently weak in your profile, so you can overcome these skill-gaps with a range of different coaching interventions. Carv's coaching includes:
audio tips after each run
ski drills focussed on specific movements
challenges to test your limits in specific skills
monitors to give you a live data feed.
