I dont think you should. These numbers appear on the ead itself and even though i dont know their significance i do know throwing out data like that seems wrong. These numbers are unique and although they can be viewable by the public thats not a justification for gathering them so impatient people can obssess about the stats and become more impatient. Changing two numbers at the end to random values, which I myself have done, is different than specifically seeking data for hundreds to see. Just my two cents.
