A number of tacks show as failed gybes in the turns stats.
The tacking track quite clearly shows an upwind turn, you can tell by the “triangle shape” and cross of directional lines and the lack of a round shaped track with no lines crossing that would indicate gybe.
Also, withun the turns actually marked as gybes, the number of failed ones is not right.
which version of the analyzer was used? You can check this by opening the session and scrolling down to the info section.
Tack/gybe classification also depends on the wind direction setting — even a degree or two can flip borderline maneuvers, so it’s worth adjusting that first.
If the issue persists, please send the original file (anchor icon in the info section) to support@sunbits.de so I can take a closer look.
