Matt,

I thought you might be interested in the attached data which analyzes the
GIBBERISH and ANTI-GIBBERISH filters by number of hits on my system from
11/15 through yesterday.

If you're looking for "effectiveness" you should set the entries in
descending order of probability.  I use a variation which looks at date of
most recent hit as well as hit count, although that's more important with
filters that are being modified on a continual rather that a fairly static
filter such as these two.

Please report any issues with the new filter format.  As soon as bugs 
stop being reported, I will move to convert the other dual file filters 
into single file alternatives which make use of the END functionality.  
Until the functionality goes into a full release, I'm going to continue 
to primarily provide the old style filters on my site.

Matt
