Usually it's a portion difference, not a disagreement. This page scores stout at a serving of 1 serving (375-425 ml); at multiple pints it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
