Based on
the $35 check that might have cost them double to send me, Oct 2012 is correct.
My overall stats for them, for comparison:
Jan 2012 to Sep 2012: 6,291 hits with 9 signups for a 1:699 ratio
Oct 2012 to Jul 2013: 5,277 hits with 4 signups for a 1:1319 ratio
So I too am in the 50% worse bracket
