      Sorry, I reversed the captions on the columns, and "my" Ham CAP SSN's are
      higher, not lower than his.

      Here's how they should look:

      Alex's Mine

      Dec 2006=11.7 Dec 2006=12.9
      Jan 2007=11.3 Jan 2007=12.4
      Feb 2007=11.1 Feb 2007=12.3
      Mar 2007=11.1 Mar 2007=12.4
      Apr 2007=11.2 Apr 2007=12.5
      May 2007=11.4 May 2007=12.8
      Jun 2007=7.4 Jun 2007=13.2
      Jul 2007=6.4 Jul 2007=13.9
      Aug 2007=5.5 Aug 2007=14.8
      Sep 2007=5.1 Sep 2007=15.7
      Oct 2007=4.9 Oct 2007=16.9
      Nov 2007=4.5 Nov 2007=18.1
      Dec 2007=3.8 Dec 2007=19.6
      Jan 2008=3.2 Jan 2008=18.5
      Feb 2008=2.9
      Mar 2008=3.1
      Apr 2008=3.7
