Coggan seven-zone model. Hover a block for time in that zone. Power is what you produced; heart rate is what it cost.
Efficiency factor
Threshold sessions only. May cross power sources — see the chart note.
Watts at zone 2
Power held while heart rate sat in zone 2, one point per session.
Average power by heart-rate zone
Weekly average watts held within each heart-rate zone, first ten minutes of every session excluded, split into a lower and upper half.
Durability
How the power-to-heart-rate ratio drifts as work accumulates within a ride, measured only from seconds inside the 56–90% FTP band so surges cannot distort it. Every ride contributes, not just long ones.
