What about Gradient Lag?

Can anyone report if Garmin have fixed the issue that the 1030+ has with ridiculously long responses to changes in gradient?

    >>>Gradient lag = elevation lag = shortage of total ascent <<<

    Not necessarily.  If it is purely lag, then total ascent and total descent will be the same.  e.g. You've crested a sharp hill and started to descend but it still shows you climbing,  That climb is still being accumulated.  I'm not saying that's the way it's working, but it is a possibility.

    it does. it shaves up to 10% of a climb on an XCO track. After a fast downhill goes uphill. Half of an uphill it gives negative grade as a result it skips the bottom part of a track. 
    I also run that track, used to have fenix 6, now it is Epix2. Every single time the watches gives the same total ascent - 55meters, but Edge 1040 on 55 meter climb gives 40-50meters

    That is not due to the gradient lag. The filtering of the data to compute gradient has no impact on what is recorded for the elevation data.

    for me the elevation data is priority #1. Never used gradient unless found out Total ascent shortage

    Total ascent shortage started in 2020 on *30 devices after some SW updates((
    Used to have Edge 830 and switched to 1040 immediately hoping the new device will be ok, but it has the same problems((

    I wanted to make sure I wasn't just imagining that 'Sensible Grade' seemed to have less lag than the default Garmin data field, so I put both fields on the same screen on my Edge 1040 and went for a hilly ride today. The 'Sensible Grade' field definitely updates more quickly and is more representative of where you are on the climb/descent. At some points on short, punchy climbs/descents, 'Sensible Grade' was several percentage points different/more realistic compared to the Garmin default field.

    I did the exact same thing earlier this week, and had the same experience that you did. I just wish the font was bigger.

    I deleted gradient tab from my screen, but I have two observations (SW 17.26) :

    1) total ascent on a hilly road course looks ok. I have to check it on an MTB course, where Edge gave the worst numbers of ascent
    2) total ascent on a pancake flat course is terrible Rage I mean there is no ascent but Edge 1040 gives it a lot

    • Let’s hope @Garmin-Matthew will return very soon, with a complete and real resolution to both the grade and total ascent issues - as promised, from the software programming team.

    Unfortunately i keep waiting since summer 2020 when these bugs appeared on edge 830

    I switched to 1040 just by only one reason - hoped the new device will be ok
