Denis,
Yes, I believe this to be true. I had a problem a few days ago where a
user was getting much more spam than they thought they should. When I
looked at their prefs, I could see that tb=1. I updated that table, to
set tb=0 and almost immediately I saw a decline in their spam. For this
particular user they had been averaging about 70% accuracy and since
then (yesterday) they have been at almost 98%. I don't think you can
always expect that much of a difference, but that setting clearly
impacts the amount of spam that comes in.
You are right though that lowering it could increase your false
positives in that it decreases the weighting to "avoid" false positives,
as I understand it.

Is it right that increasing "tb" will decrease chance of false
positives and decrease Spam Hit Rate?
