Power meters can often be calibrated wrong and can throw up incorrect readings. These readings can throw off all of the value add performance stats details in the connect app including Training load, training status, power curve, FTP, VO2 Max and Training effect.
There should be a way of removing these incorrect readings retrospectively and then recalculating all value add reading from that point to date. Other tools like training peaks can do this, why cant Garmin Connect do it?
Basic requirement for any tool which provides performance metrics and training guidance.
