Usually it's a portion difference, not a disagreement. This page scores custard at a serving of 1/3 cup (85 g); at 1/2 cup (125 g) or more 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.
