Spot on. Have a cigar!
The scores on the doors (using set 4): NO_REAL_NAME 0.007 INVALID_DATE 0.236 HTML_COMMENT_SAVED_URL 0.146 BAYES_99 3.5 HTML_MESSAGE 0.001 HTML_FONT_BIG 0.142 MIME_QP_LONG_LINE 0.039
The scores for each rule, when added together, are 4.071. Hence a total score of 4.1 (rounded) even though the individual rules when rounded before addition only score 3.9.
Perhaps it would be useful to add this little quirk to the wiki? On the RoundingIssues page?
Thanks again for all the help!
