In my document I have a
Underfull \vbox (badness 2662). I want to ingnore this specific badbox but none of the others. Therefore, I want to make LaTeX locally less sensitive to badboxes. I tried
\vbadness=3000 <some code> \vbadness=0
where the last command is intended to turn the "ignore badboxes mode" off again. However, I then get a lot of "badness < 100 or somehing like that" messages, which I didn't get before. I suppose
\vbadness=0 is somewhat too little.
What's LaTeX's default mode, I mean, if I don't interfere at all which is the badness threshold under which LaTeX doesn't complain?
