Hi Matthias,

I noticed something after the last update.

During the windsurfing session, WST shows a maximum speed live (e.g., 42.8 km/h for me). After the session, in the evaluation, only

Hi Heiner,

The live display during the session shows an unsmoothed, roughly checked value (usually on a 1s basis). This 1s value is not saved and is intentionally not included in the evaluation anymore – it is too susceptible to GPS outliers to be reliable. This has changed compared to V1: there was only this one unchecked value.

In the evaluation, you will instead see the “Best 2s” value, which has been plausibilized and which we consider a more reliable comparison value.

For your challenge, I recommend increasing it to at least the 5s value – the 1s value from an app doesn’t indicate whether it was a real peak or a GPS outlier, and it’s hardly comparable fairly between different devices/apps.

Best regards  
Matthias
