The power accuracy of smart trainers and third-party power meters may be affected by various factors.
The power reading of the smart trainer is calibrated during deceleration. Please note that no two power meters give identical readings. Multiple identical simultaneous broadcast power meters have been empirically proven to report different power data, even during the same exercise process.
The factors that contribute to this difference include:
● Freedom of motion
● Data transmission rate
● Packet loss
● Wireless interference
● Sensor or strain gauge position
● Differences during calibration
● Accuracy tolerance
● Leg imbalance
In addition, the power accuracy tolerance of the smart trainer is combined with the tolerance of the power meter. This means that if the power accuracy of the smart trainer is ± 2%, and the accuracy of your power meter report is ± 1%, then at any given time, the total combined accuracy tolerance will be ± 3%.
