[craig@belphegore masses]$ fgrep X_NOT_PRESE analysis 0.002 12 -1.9200 X_NOT_PRESENT 0.076 469 -1.9200 X_NOT_PRESENT So it's in 7.6% of all false negatives in the corpus, and 0.2% of false positives. The ratio of FN:FP should be about 12:1 according the the way the GA weights things, so the actual 35:1 ratio is way, way off. This should certainly be fixed, possibly by just dropping the rule altogether. DQ> I also have some good headers ready to check into HEAD for "clawing DQ> back" functionality.
