After putting todays 5 by 10 average off my realspeed printout on team challenge site i then went and typed my results into GPSSS and found my 5 by 10 average was actually higher i confirmed this with a calculator.
checked settings on realspeed division and all appears right but the result it gives is wrong
GPS results is the same as realspeed for this but different in many other divisions
which is the correct result
using realspeed 1.924 with navi firmware 1.62

Email your track to info at gpsteamchallenge.com.au and I'll take a look.

I found I wasn't clearing my history in Navi

the navis display is not to bad but for me it's to much frigging around, Max speed and keep resetting

problem sorted
didn't have the one result per run box ticked so the 10 sec speeds on the printout were off two runs only where as the realspeed time was the correct result using one result per run
