Strange Times on Data Graph and Session Details

Post by rcrider13 » Sun Dec 05, 2010 4:11 am

Version: 3.0.8 Beta 3
Device: Polar S520

When I upload my data the HR zone distribution graph in the "Session Details" plane does not show the correct times based on the workout length. I have attached two screen shots which show workouts of 30 min but the total time on HR Zone breakdown is greater than 30 min.

Another strange thing is that when I go to the "Data Graph" the total time in the graph will be greater than the exercise time. I have attached another screen shot of this.

Is this an issue with my HRM, an issue with the sample time on the HRM, or a software issue?

Thanks for the help.

Hi,
This is caused by the way that the S520 changes the recording interval as the duration of the session increases. The same bug will also happen with sessions that are a few seconds longer that 1 hour as well. So far, we haven't managed to work-around it, and it's looking unlikely that we will without input from Polar, which isn't likely to happen.

The "fix" (if I can call it that), for the moment, is to make sure that your sessions are not within a few seconds of 30 minutes or 60 minutes in length.

Regards

Stuart
