5 x 10 sec Question to the guru's

Just wondering about 5 x 10 sec avg's, I'm not the fastest out there but out on the weekend had a nice sail and did one long run close to 2 nm total of 13 km, when got off the water I checked the restore on the max 10s avg on my GT 31 and I had 5 over 20 kts, so I thought that I would of had a 5 x 10 of atleast 20 kts but when I downloaded the file I only got a 5x 10 of 16 kts with a nm of 18 kts.Wondering if someone could explain it to me why?

^^^^^ what he said, but also the speeds have to be from the current session.
The restore function will show you the best speeds from ALL the sessions you ever recorded.
So some of the 5 averages you were looking at were probably from previous sessions.

The GTs set on speed genie will start a new calculation, every time you drop below the set speed, so if your trigger speed is 20kts, and you fall under 20kts 5 times, then go over again on your long run, you'll get 5 runs over 20kts on your 10s max average.
But real speed needs you to change direction, (I guess this is the definition of "a run"), before it starts a new calculation, so from your long run it will only give you one 10s result.

And as already mentioned, if you haven't zeroed the last session, that will be there as well.

I had zeroed my last session so it was showing no restore figures for that reason as I have been fooled before on to that one. I guess it sucks if you have one good run and then find all the holes like I did on the weekend. But still it is good to know for the next time I go out Thanks for the insight

Thanks for the help will keep that in the back of the head for next time. Need to perfect the 360 then.
