Quadrant analysis

Is there any way we could get a Quadrant analysis chart.

I know that i can’t get CPV vs average torque, but we could plot (as a scatter chart) torque vs cadence.
(BTW i am not an expert or anything like that, but i know enough to be dangerous, but maybe not useful)

Yes quadrant analysis is already on the todo list. Thx.

Hi David,
We all know that you’re extremely busy, and was wondering if the quadrant analysis will be a feature sooner than later, please?

For those that don’t understand it,:

  • Quadrant I (upper right): High cadence, high force. Sprint type work;
  • Quadrant II (upper left): Low cadence, high force. Hill climbing work;
  • Quadrant III (lower left): Low cadence, low force. Easy pedaling (in the pack or during rest periods between intervals);
  • Quadrant IV (lower right): High cadence, low force. Fast pedaling with little resistance (sitting in the middle of a pack or pedaling downhill.

I copy the formulas from wko5 in case it can help in its implementation.

Q1
sum(if(cpv >= tcadencecranklengthpi/30000 and aepf >= bikeftp/tcadence/pi/cranklength*30000, deltatime, 0))/sum(if(aepf>=0 and cpv>=0, deltatime))

Q2
sum(if(cpv < tcadencecranklengthpi/30000 and aepf >= bikeftp/tcadence/pi/cranklength*30000, deltatime, 0))/sum(if(aepf>=0 and cpv>=0, deltatime))

Q3
sum(if(cpv < tcadencecranklengthpi/30000 and aepf < bikeftp/tcadence/pi/cranklength*30000, deltatime, 0))/sum(if(aepf>=0 and cpv>=0, deltatime))

Q4
sum(if(cpv >= tcadencecranklengthpi/30000 and aepf < bikeftp/tcadence/pi/cranklength*30000, deltatime, 0))/sum(if(aepf>=0 and cpv>=0, deltatime))

Not to be a PITA but it strikes me as something the folks at Training Peaks/WKO might not be so keen on being copied since it is proprietary. Just sayin’
