You asked about the WKO vs Intervals data analytics. At a point in time, the quadrant analysis wasn’t available in Intervals, but it is there now. The rate at which stuff is being added to Intervals is unbelievable, so the gap between the two tools is closing.
Steve Neal (FTL forum host) gave some good advice with analytical tools, and I’ve learnt to use WKO, Intervals as well as Xertonline, and they each have their own good points. No perfect system, just a different way to view data.
Here’s the post from David with the Quadrant Analysis chart showing. It’s great tool to show the athlete how their power and cadence relationship is, during a ride; base period has some low cadence, high force.
Therefore it’s important to understand where to find the different charts, as some are workout based (only shows against a workout) and other’s are athlete based (shows on the fitness tab).
