How did you determine that the A2 was more optimal than the S2 in most cases? Did you look at boat speed vs wind speed, how you did relative to other boats or did you use some other technique? I don't think there is any way I could tell how thrust vectors differ between a sym and asym just from sailing the boat.
Does anyone know what the state of the company that developed RaceQ's is? The service is working for me but it looks like the iPhone App has not been updated for 4 years and also the Facebook page and the forum on their website seems to be pretty dormant. This may be a long shot but does anyone know how to contact the developers?
