sailquik said..A fast gybe seems to just have that radius to come back square to the wind with a little bit of margin. It was just trial and error by Mal Wright (who invented the concept and defined the algorithms) and a few others and we just thought that was about right. Time has confirmed it.
We also experimented with @250 and @1000, but @500m seemed to be about right too!
That was great work by Mal and you guys, I just love the alpha category, it's a great combo of skill and strategy, of course using alpha markers is cheating a bit, but it all adds to the fun.
The main problem I've become aware of lately is what happens to the data from an arm worn unit. In some cases it can be pristine with very low sdop numbers and trackpoints and doppler traces completely overlapped. In others the data into the gybe entry is very degraded.
Salty nuts has been doing some experimenting, wearing 3 GT31s, in different places. I think I'll start a new thread about his results.
