Big difference in passed time between points after map matching

Hi everone,

calculating the absolute time passed over a distance of 58,2 km by summing up all the time values I get from the path details shows a difference of 26.5 minutes compared to the absolute passed time I get from my original data. Can anyone explain how this time value indicating the passed time between to points gets calculated by graphhopper? Or can someone recommend better way to get a better matching “timestamp”.

Thank you in advance.

Best regards

Martin
