Strava does that now even if you don’t have a PM?

In concept, it should be OKAY on hills if it has excellent altitude data, and on flats if there’s no wind. Even light wind on flats could totally screw up the outcomes.

Expected energy curve begins at 1 min. It assumes that the most power you can keep for 1 continuous minute is 450 W. It’s fairly feasible for you to hit 700-800 for a few secs if you try.

From interest, I attempted to publish one of my flights with energy information stripped. Power curve was respectable (though it underestimated power by 10-20 % in the area where my peak energy was achieved while climbing up a hillside in to headwind). Ordinary power and total job were quite close. Energy circulation graph was way off and it didn’t also look as wonderful as yours.
