Course profile, normal for our rides:
That's how one gets/stays strong. Those are HR zones, not power, but I don't drift much this late in summer. .
I absolutely guarantee you your power was in z1 for way, way more than 10%. Probably higher than 30% on a group ride with a course profile like that.
Another example of where heart rate falls short. You just don't realize how easy you pedal a lot of the time without a power meter. It's an eye-opener.
ETA: I noticed you said you coasted for 12% of the ride. So yeah, if coasting amounted to that much, then easy/soft pedaling/z1 will include that and be much higher.
