I'm trying to figure out the 2 sec calc because today I got 7 readings in a row:
29.28
30.25
30.67
30.27
30.22
30.52
29.59
but my RealSpeed and KA72 2 sec peak is (
http://www.ka72.com/TrackRecalc.aspx?fid=32417)
29.89
I found a post from TimeMachine (RealSpeed author):
www.seabreeze.com.au/forums/Windsurfing/Gps/Bug-in-Real-Speed
40, 42, 43 (wishful thinking in these windless days I know...)
The two second result should be calculated as follows:
((40+42)/2 + (42+43)/2) / 2 = (41+42.5)/2 = 41.75
So mine would be
((30.25+30.67)/2+(30.67+30.27)/2)/2=(30.46+30.47)/2=
30.465Using GT31, latest firmware.
What am I missing? Something to do with Doppler?
