I ride off-road in Maryland over roots and rough terrain w my sensor in front. I sometimes lift my back heel high just to retain balance specially riding horizontal across a slope (as in the East/ West of a hill if up and down = North n South) .
The computer does know to disregard the single sensor function above I think 5mph or so. I've tested. I have also found myself navigating slanted terrain at about 3mph and having to dance up pretty tall on the board and was def cut off leading to a letdown understandably
