Thanks for those data points. I agree that of the two numbers I'm getting for my rides, it's likely the calories that aren't as accurate and the energy is likely closer. This statement is based on my perceive effort vs. calories and energy for road bike rides with power meter.
Elsewhere it's been noted that Strava simply imports the calculated calories from the calculation done by the head unit (can anybody verify?), but I don't see what settings (rider weight, etc.) could be so far off on my head unit. And if that's the case, from where does Strava get the energy calculation? So I'm puzzled.
