Usually it's a portion difference, not a disagreement. This page scores cheerios at a serving of small portion (about 1/2 cup); at full bowl 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.
