Also how come the polars also have a lot of info for square reaching. IMHO we almost never go square to the wind by choice. Is this recorded as the rider bears away??? or is it just a phenomenon of the averaging process of the program? Also does the outer butterfly plot max speed vs direction or is the speed taken over a period of time -say 5 seconds or something else. Gunnar's bursts past 30 knots are impressive but only so if sustained.
You can tell GpsAR what the true wind angle was, there's a setting somewhere I used once. Thing it, it's still not going to give you totally accurate polars. To do that you'd need some kind of device measuring wind direction on the kite, or at least on you. Boats do this, America's Cup boats spend a lot of money and have instrumentation all over the masts to try and work this out.alexrider wrote: ↑Wed Apr 12, 2017 7:53 pmI am not sure of that. To show apparent wind, you the value of the real wind must be fed. Will need to check if somewhere in the program you're supposed to give the wind speed. I wonder what assumption (in case you don't feed in the wind speed) the program makes to show the wind vectors. Good you pointed this, it would have escaped me.
