it's just a compass and tells him which direction he's facing

You don't need to stop sprinting to eat... still in my opinion an advantage from those who don't use it. You could be running endlessly, while the person behind you has to stop every 3 mins of the chase to fill up the hunger normally.

at around 0:50 when the video speeds up you can see him slow down when he eats, something which every other player does
