I had a quick look threw one in a shop not long after they came out, you could just make out the unlit dots and it appeared as tho there where a few separate dots as opposed to a continuously variable dot IE a dot for say 350-420 next dot 420-500 or some thing like that.
I could be wrong it was only a quick look,but if that is how it actually works elevation could be a bit high or low at some ranges for a hit on a bunny
