Yes, that would apply.  "bogofilter -q" will show what
parameters bogofilter is using when scoring.  Most likely
the default values are in use.  

To see how a message is being scored, use one of the
following commands:

   bogofilter -vv < message
   bogofilter -vvv < message

The output is described in the FAQ.
