Serious bug in drop calculation

Fransua

Hi; I think I have a bug on the drops calculation on my last outing. Runalyze indicates more than 1000m of vertical drop when my other instruments are at 750m; It's a route I know well and it's not 1000m; As in general your calculations are good, and the original Coros file gives 870 m, there's a problem.
Any software modification made ?

Please read how elevation is calculated: https://runalyze.com/help/article/elevation?_locale=fr
And you can always use https://runalyze.com/settings -> Activity view -> Show "Prefer ascent/descent from file", if you want to have shown the ascent/descent the vendor writes into the file
