For those of you who haven't seen what Rosco757 is talking about, what I found when I charted the straight Date workup hits was that they tend to clump together two days apart. Sometimes it's one day and sometimes it's three days, but by far the most frequent gap is two days. So I started watching for these (and so did Rosco757). Here is the chart that shows a couple years worth of this happening:

Start to see a pattern there? LOL! Obviously, these don't happen every day of every week. Sometimes there a long gaps between, but this is one of those plays that sometimes can help narrow things down significantly.
