Incoherent distance after speed sensor installation
I was experiencing an issue after speed sensor installation (Decathlon by Magene -> configured with correct wheel circumference). On usual tracks recorded distance is always less (distance was inferior) than:
- Same Karoo and same ride before speed sensor installation
- Distance expteced based on portal where i take gpx (Komoot, Wikiloc)
The less distance is near to 2 chilometers every 50. Not clear if could be an issue but i would like to be sure about ride distance.
Any idea on this?

Is your sensor connected via ANT+ or BT? BT/BLE speed sensor connection is terrible: it looks like data points are lost, which causes underreporting. This issue is prevalent even when using auto-calibration (which is really strange). I was in touch with support because of this and they promised to solve this issue, which they never did (according to the changelog), which is really disappointing. I made sure that all my speed sensors are connected via ANT+: this works as expected. When using BT/BLE, auto-calibration isn't even worth considering, and manual wheel circumference means that you have to try too large values in order to get correct distance readings. In my case, I had to use ca. 2180mm for 30mm tire.
