No. Scores are not determined by how many spams a rule hits. Scores are
automatically generated to correctly flag as many spams as possible
without exceeding 1 false positive in every 2500 hams (with a
required_score of 5).
Stated in
http://svn.apache.org/repos/asf/spamassassin/trunk/rules/50_scores.cf
(a file you get via sa-update)
So it's entirely possible to have a rule that hits a very small percentage
of spam with a very large score.
