Tuning the Programmed Wind Direction in VMG Mode
Use the following guidelines to adjust the wind direction programmed on the SC-1 when you are sailing
upwind:

If the indicated VMG seems like it's consistently higher on starboard tack, increase the value of
the programmed wind angle.

If the indicated VMG seems like it's consistently higher when you are on port tack, decrease the
value of the programmed wind angle.
