I have a much smaller collection. I was going to send it but
Bernard Stern was quicker and I don't believe everyone on the
list should add their own column :-)

I don't think much information can be extracted from yearly
summaries. They just say 'UBE is increasing' -- we knew that,
though the pictures are nice.

Short-term statistical analysis of particular features of UBE
can be helpful in the arms race, as all filter writers know.
The bulk mailers' techniques and targets change every few weeks;
perhaps they do their analysis too ...
