### Average Power discrepancy

Posted:

**Mon Jul 27, 2015 5:46 am**Hi OMB,

I am noticing a discrepancy in AP figures in the Critical power tab.

As you can see in the attached image, CP20 for this ride is 228W, while the average power for this segment in the graph above shows an average of 233,7W.

Since the graph value is higher, my initial assumption was that maybe calculation of figures in the graph are done using the Standard ST AP calculation, not including zero values... but I am finding other instances where graph averages are lower than corresponding CP values, which kind of ruins my theory (see second screen grab).

Can this possibly be a bug, or is there an explanation I am missing?
