Except that the OP did not speak about distance but about "the length between some overlapping numerical ranges", this phrasing does not really make sense to me. The length between overlapping ranges, if anything, is 0. This is why I kindly asked for clarification. Or, perhaps, it is a deficiency in my command of the English language. But the OP answered some later posts by other monks, but did not see it fit to answer mine.
