One of the first lessons I learn long, long ago as a youngster just because "it has worked" doesn't mean it's right. You could have lucked out, or you could have not known if it was exactly 0 degrees. What ever the case when automotive theory is telling me to set them at a couple of degrees, that is what I will do.
