What is the GPS world record based on.
I did think it was your best 10 second run but when looking at Craigs stats the world record time doesn't show up in his 5 best 10 second times.
Also are National records the same.
see here Martyn under the record rules pdf file on the page http://www.gps-speedsurfing.com/default.aspx?mnu=item&item=RecordRules
We take the best 10sec from the record session based on the calculation of the 10sec from 2 GPS.
There is also a deduction for the error margin which then becomes the Claimed Speed!
Thanks Roger that clears it up.
