Actually no.  As several others have pointed out, the methodologies you used
to gather "quite a bit of data" and the conclusions you reached are
seriously flawed for a number of reasons.

You cannot determine that they are "specifying valid data in the attribute"
unless you inspect the value of the attribute and the page itself *by hand*
to determine whether from a human perspective proper semantics are being
followed.  I believe other folks (some with accessibility expertise) have
already pointed this out.
