Hi Guys, how can I analyse laps if points of speeds measures are all the time different??? Why on one lap i have many points of speed points and on the orher much less? Thanks Karol
Those are high and low speeds of the lap. The position is different as the position of high and low speeds are different. This means your braking points and beginning of accelerations are different. You should use the graph for analysing speed at certain point.
Must be GPS problems if you're full acceleration at that point. The map looks pretty good though, but as you don't have the satellite imagery at the background I cannot say how accurate it is for sure. The GPS data is never 100% accurate, and when there's odd things such as this, or trajectories not matching the satellite imagery, you should trust it even less. Also the map view doesn't tell much though, I think you should be looking at the graphs as well as the map.
Its race track Poznan in poland and its flat. Ok, i will try to move xgps160 in different position. Lap times are very accurate racechrono vs sensor I have on board during the race. Only speeds are much different.
Can you share some of the sessions with the problems to me at tracks(at)racechrono.com, please? Also please tell me which corners/straights to look at. I'll check if the recorded data is trustworthy.

Please let me know what is going on the last corner before the start/finish?????
I wonder why racelogic is working fine?
