Thanks, below is an example from one of the runs, they are all similar to this one:
So there will probably be a few things you will end up investigating, but to start
the "cda chart" is actually a rolling CDA and is calculated on a 60 sec window. So for example the value calculated at 12km is made up of the data for the previous 60 seconds.
At 60km/h it will take 60sec to do 1km. So all the points between 12km and 13km is made of diminishing data from before 12km. Why your CDA is 0.1 at 12km is probably bad data and we would have to see the data between 11km and 12km to figure that one out.
You can set the window to 30sec (or 15) and you will see the CDA stabilize quicker and it should be stable from 12.5 to 13km. It may be higher than you'd expect but you would then need to figure out what is causing it.
