I've noticed a discrepancy when auto posting to GPSS and from there to GPSTC using GPSResults in the distance and hour.
GPSResults had a default filter setting I had mine set to 1knt but everytime I auto sent my results it reverts back to a 5knt minimum don't know wether other GPS software is the same but it makes a big difference.
My last session I did in distance 68.92km with the filter set at 1 knt when I auto sent the data to GPSS it was recorded at 61.37km and my hour went from 19.40 to 18.97.
I uploaded the file to KA72 site and it gave me a distance of 69.26km Vando checked the file on Real Speed and it showed 69.45km.
When I'm out on the water floating around waiting for a gust doesn't this count as sailing?
Maybe we should all use the same program to upload times to GPSTC like KA72? this way if someone sails over 100km in a day they are not going to lose 10-15km out of their session if they happen to drop below a given filter setting.
Don't know wether the same happens with GPSaction replay or Real Speed when auto posting but it's food for thought.
