I used my 910xt to record some laps at a motor racing circuit at the weekend, when I come to review the data, if I look at it on the dashboard the route trace line follows the circuit fairly accurately (within what I would consider to be reasonable levels), when I go into the player to have a look at hr levels at different points during the race I just get a spiders web of straight lines missing large sections of the circuit. is this a setting that I need to change?
