The DATA POINTS on Run Cadence (SPM) chart on the "details" page are color coded. There are red, yellow and green data points. There is no key to explain the color coding, and there isn't anything obvious about the data that correlates with the colors.
What do the colors mean?
A follow up question - where do I find information of this sort? I looked through the "help" pages and the "features" pages and there doesn't seem to be any detailed feature-by-feature descriptions with call-outs, etc. to explain the data.
