To summarise what the 2007 POOMAs were all about:
1. I chose 20 of my completely mechanical systems to run for the year;
2. I did two system reviews, deleting some and including others at each review; and
3. Results were broken down as TOTAL (allowing for selections that came from multiple systems) and UNIQUE (single selection regardless of how many systems selected it).
The worst thing I did was to cull System 13 at the first review, as it went on a terrific burst from that point forward and got itself back into the black (which I had even predicted when I culled it). As a POOMA it finished at -9.5% whereas for the year it achieved +7.3%. At least I got something out of it after reintroducing it for the final review. The best thing I did was introduce Systems 22 and 25, which were strong contributors.
I'll have another post describing the 2008 POOMAs, which will be based on those successful through 2007 plus a couple of others I've been tracking along.
The following is the summary of the 2007 POOMAs broken down by various categories:
