Grade inaccurate since 24.20

After updating to 24.20 I'm now seeing inaccurate grades being displayed.  When going uphill I'm getting negative gradients and going along flat shows 6%/7%. On Climb Pro in a red sections just 6%.  It was fine before the update.

    This mistake SAS introduced in new algorithm  to be more responsive.. but is terrible inaccurate… even in Sw version 24.19 for garmin edge 840.

    we hope in in quick fix

    I agree.

    garmin should have fixed this new algorithm to grade determination as soon as possible

    This seems correct: the grade reading changes much more often than it used to do. But I think that introduces all kinds of over-correction errors as it tries to keep track of changes. So I get negative readings while climbing, or rapid fluctuations on a steady grade. The best quick fix would be to go back to the old algorithm, which wasn't super responsive, but had the minor benefit of being approximately accurate, on the  whole (thought it also gave weird results or exaggerated, sometimes.)
