[Dspam-user] Does this make sense?

Plexus LLC
So I am trying to understand what is happening with my dspam install and why it is working well for some users and not at all for one.

I created a dspam user (intended to be corpus fed and used as a merged group), following this tutorial from Stevan: http://sourceforge.net/p/dspam/mailman/message/29158188/

I fed it some spam and ham and then started testing to see how it does. Below is a result that I don’t understand. Shouldn’t the FN be incrementing instead of the TN when I feed it a spam with “—class spam”?

(the email that i am feeding it, “test-3”, is a short spam message which has no dspam headers)

# dspam_stats -H dspamr
dspamr:
        TP True Positives:                 12301
        TN True Negatives:                  1358
        FP False Positives:                    5
        FN False Negatives:                  191
        SC Spam Corpusfed:                     0
        NC Nonspam Corpusfed:                  0
        TL Training Left:                   1137
        SHR Spam Hit Rate                 98.47%
        HSR Ham Strike Rate:               0.37%
        PPV Positive predictive value:    99.96%
        OCA Overall Accuracy:             98.59%

# cat test-3 | dspam --user dspamr --mode toe --class spam --source inoculate --stdout

# dspam_stats -H dspamr
dspamr:
        TP True Positives:                 12301
        TN True Negatives:                  1359
        FP False Positives:                    5
        FN False Negatives:                  191
        SC Spam Corpusfed:                     0
        NC Nonspam Corpusfed:                  0
        TL Training Left:                   1136
        SHR Spam Hit Rate                 98.47%
        HSR Ham Strike Rate:               0.37%
        PPV Positive predictive value:    99.96%
        OCA Overall Accuracy:             98.59%

#cat test-3 | dspam --user dspamr --mode toe --stdout --classify
X-DSPAM-Result: dspamr; result="Innocent"; class="Innocent"; probability=0.0000; confidence=0.76; signature=N/A
