My 255 has developed a minor annoyance. I go for a run. My watch reads 2.51 miles. I sync without issue. I then look at Garmin Connect, and the synced mileage is 2.47.
Again, not a major issue, but why would this be happening? I use a Stryd pod, if that helps.
Any ideas. And there are no third party datafields except Stryd.
Thanks
