I knew about those two, but they're phrased differently than the {rav/'aqroS} construction. The {rav/'aqroS} construction puts the {rav} before the value of the lower bound, and is used in a larger sentence. Those two examples have {rav} at the end of the thing whose bounds are being described, and are used in a sort of standalone "label noun phrase: value noun phrase" context. They're different enough from the {rav/'aqroS} construction that I didn't think they'd work so well as supporting evidence for using half of a {rav/'aqroS} construction by itself.
