If you read the article, you'll see at the end of the second paragraph they say they are using smart recording.

 

 

 

Smart recording uses GPS points to reduce the number of samples that it records - e.g. a straight road, the gps will just record the start and end point, and the time taken between the two.

 

 

 

The problem is that power samples get dropped, so you have no idea whether the rider was coasting or pedaling.

The smart recording, as most of you know, isn't so smart for Power data. Our mistake, won't happen again. Changed them ALL last night!
