I noticed that you can change your 1 hour result by deleting slow points in realspeed.
Mine is set to .85 NM in Realspeed which seems to be the default.
My GT31 is set to not record under 3Kn.

Questions: Should everyone have the same setting on their GPS & the same default setting in Realspeed so as we are comparing apples with apples or am I just totally confused.

If you set the gps to not record under say 20 kn you would then get a really good 1 hour wouldn't you?
Probably no alphas though

Any thoughts / explaination welcome but try & keep it simple if possible
