Targets are not validated specifications
A design target describes what the product is being built toward. It should not be read as a final guaranteed production result.

Accuracy, validation and product limits
Sensor performance, battery life, water resistance and other specifications remain targets until the relevant production testing is complete.

Accuracy depends on the metric
Heart rate, HRV, sleep estimates, motion and temperature each require different validation methods. A single accuracy number cannot meaningfully describe the entire product.
Real-world conditions matter
Fit, motion, skin contact, environment, firmware and user behavior can affect wrist-wearable measurements.
Certifications are stated only when complete
ARC will not claim FCC, CE, UKCA, Bluetooth certification, RoHS compliance or a specific water-resistance rating until the relevant production work is actually complete.
General wellness, not diagnosis
ARC is being developed as a consumer wellness product, not as a diagnostic medical device.
Published production documentation wins
When final specifications are released, use the current product page and production support documentation rather than old concept material.
