Frequently Asked Questions
Why does Zwift create blocky elevation profiles on Strava?
Smart trainers update resistance in discrete gradient intervals, creating artificial steps rather than continuous curves.
Will normalizing Zwift elevation keep my power and cadence intact?
Yes. FitCrop only smooths altitude data points; all watts, heart rate, and cadence records remain untouched.
