I have a new power meter on my MTB, (Stages XT dual sided) and recorded some rides with it now. I love having the power data when i’m on my MTB but the data between Garmin and TR/Strava/others isn’t the same. (recorded on a Edge 530) The AVG power and thereby the NP, TSS, IF and KCAL’s are differe…

Went digging and i can see that Garmin isn’t including all the data sets when calculating the averages. But cant find a explanation/reason why this is happening. If i include all the timestamp’s into a single file. The averages are the same across the board. But GC isnt doing this… UGH!

@gpl Think we’ve found the answer to this problem. “ Incorrect average lap power - Edge 1030 Plus - Cycling - Garmin Forums ” “So this gets a little complicated, but the difference is due to a couple of things going on. One is that there are radio outages that are causing some of the records to be …
