I was under the impression that the use of WSJ data was adopted
because it is easily verifiable and reproducable, after all there
exists a PRINTED copy of the newspaper for any given day. I am not
sure you could "reproduce" the national debt (for example) at a given
point in time if someone disputed the result and wanted to run the
algorithm themselves.
