GPX files carry no foil sensor, so flights are found from speed. You lift off once speed reaches the take-off speed and count as foiling until it drops below the touch-down speed. Anything above the driving speed for more than a few seconds is treated as a car and removed, along with the slow-down and speed-up around it.
Each session is then trimmed to its downwind runs. Your flights show which way downwind was, and a run is the stretch where you were heading that way, from the paddle-in to your first flight until you stop or turn off the line for more than four minutes. Paddling out across or against the wind, waiting, walking and driving are left out. Walking is recognised by its unusually steady speed (2.5 to 8 km/h, varying by less than 0.3 km/h over a minute, for at least 90 seconds) and by where you are: it has to be on land or within 50 m of the water's edge, using OpenStreetMap's shoreline. A smooth paddle out on the water stays a paddle. The shoreline is fetched from OpenFreeMap the first time a spot appears and kept in this browser. Travelling 150 m or more back upwind between flights starts a new run.
