I have a question regarding a 3 sensor setup. I see that it tells you to place the third sensor in one coroner behind you, but I'm curious to know if that would mean you'd get jumping or jitter when facing the corner without a sensor behind you? Does it also mean you would have to turn the same way toward the 3rd sensor behind you each time you turn around 180°? I assume if you turned from the front facing sensors to the corner without a sensor this would cause problems, wouldn't it? I would imagine you would get jumping and jitter?
