Assigning score to custom rules (and rules in general?)

[Blaise St-Laurent]

I was wondering how more experienced spamassassin admins have been 
assigning scores to rules that are relevant to their site (and also per 
user if need be). I've installed a few "aftermarket" rulesets now, and 
some of the values are (IMO) either too low or two high based on how 
many show up in the spams and hams i examine.

Is there a good methodology to figuring out appropriate scores? I was 
thinking of writing a script that would look at the proportion of  
ham/spam that this rule applies to, but that gives me a percentage, but 
not a value.

How are you all doing it?
