On the activity page, would it be possible to show gradient as a colour across the (similar to Veloviewer), so that, I can see that, at a glance, that power reduced for a section as the gradient eased (or vice-versa; that power spiked when there was a kick in gradient).
Obviously, I can mouse over the area and see those details, but to see at a glance over the course of a longer activity/interval/effort would be useful.
EDIT - in practice, I would use it similar to the Grade Adjusted Pace in Strava over the course of a segment/interval.
Gradient data can be very noisy indeed, there’s definitely a need for smoothing.
I would limit it only when actual barometric data is present, as GPS adjusted elevation has often big gaps and steps.
Unless you’re crossing path with a hurricane, barometric pressure changes way slower than you can climb. I can show as an offset on a longer climb but should not affect grade, so it’s an error component, not noise.
