Speed reading accuracy?
Hello , I was out on my bike the other night and filmed a descent . I know it was fast and do not use any kind of speedometer ,instead I rely on the speed devil feature from my Banditcam . I would like to believe that I went + 50 mph the other day but the fluctuations in speed moments before make me doubt if I did hit + 50 mph . The following clip shows speed dropping then jumping real high . What was happening and are any of the readings accurate ?[video]
