Quite correct. The default (from crm114.pm) is
  my $default_crm114_dynscore_factor = $conf->{required_score} / -25;
... which aims at calculating a normalizer value that would put a CRM
score of (-)25 at your required SA spam score... I think this might
not be the best of things, since the values can fluctuate quite a bit
more than that, and I imagine most *don't* want CRM114 to be the sole
deciding factor.
Anyway, did you install according to the wiki page? If so, I obviously
have made some changes that I've promptly forgot about(:-)... else the
"default" in the crm114.cf file was what I mentioned.
