AeroPod, PowerPod and Newton

Two observations thus far when pairing the Newton with a DFPM (Power2Max) for the benefit of CdA analysis...

1. Every ride I analyse with the "CdA Analysis" feature shows a flat line for the first 4-6 minutes of a ride. This is systematic and not the result of strong winds or low ride speeds.

2. Why do I get two different CdA values for a 6 mile DFPM calibration ride when comparing "Check Calibration" feature with the "CdA Analysis"?

I've submitted the calibration ride file to illustrate these two observations.

Hello again,

Has there been any progress or analysis based on my observation? I bought the Newton on the strength of its proclaimed aerodynamic functionality (in particular CdA feedback and analysis) but unless I'm going wrong somewhere (and please correct me if I am) so far I don't have much confidence in the Newton's ability to provide me with accurate CdA data.

One of my roles is product testing and research and I would very much like the aerodynamic features to work (I've invested a lot of time and my own money in doing so). Please assist me with my objective.

For the record I am using a standalone Garmin speed sensor, standalone cadence sensor and 3 DFPM (Power2Max, Rotor Power and Rotor InPower).

Best regards.

We missed your first post.

Give us a chance to investigate and we will respond.

Thank you, much appreciated.

In the meantime, I am going to upgrade to Newton 5 to see if that eradicates the problem.
