You might be interested in visiting the AntiSpam-Tool Leage Table. And perhaps, in subscribing to the weekly newsletter. It is all full of numbers, statistics and ways of determining the effectiveness of the antispam tools. You could copy their ways of recording the data and later compare notes with their compendium.

I have also read an article at ACME that adds another factor to the antispam equation: CPU time.
