since Strava no longer notifies losing 1st place on a segment with grade lower than 0.0%, can we have some sort of mechanism that;
- filters activity data where GPS resolution is < 1sec (eg, garmin 'smart' mode)
- filters > 95% peaks / troughs. (outliers)
- averages the observed gradient change in remaining activities for that segment, and updates the segment gradient profile accordingly. (not absolute elevation, just profile)
many antique segments were created when GPS recording for sports activities was wildly inconsistent, and many are incorrectly considered uphill or downhill.
