Usually it's a portion difference, not a disagreement. This page scores frosted flakes at a serving of 3/4 cup (30g) of a malt-free version; at large bowl or barley-malt version 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.
