Well, I could explain but then I'd have to kill you ;-)
I'm really not sure what algorithms other software
currently uses, but my understanding is that we
have a big advantage by using ASI as well as GPS.
Happy Holidays and Best Regards, Dave

My experience is that the wind calculation of the SN10 is extremely
reliable and accurate. I reckon WP is as good as any other device
calculating based on circling drift only, like the LX20 for example. I
often compare SN10 and LX20 values and normally the SN10 is far better.
I'm sure Dave N. can explain why.
