I am a user of the ULTRASONIC Portable Mini and I am using the Sailing mode of the Anemotracker App. The diagrammatic values of Apparent Wind Angle (AWA) and True Wind Angle (TWA) do not match the degital values of ANA and TWA. For example, while the degital value of AWA is -48 degrees, the diagrammatic arrow of AWA indicates approximately -68 degrees. At the same time, while the degital value of TWA is -90 degrees, the diagrammatic arrow indicates about -72 degrees. Please modify the diagrams.
