How much you lack? 

It means, "how much do you have remaining?"

If you're waiting on someone to do something, you may ask them this to get an idea of how much longer it will take for them to complete their work.

In the Southern United States, the word "like" will be used in place of "lack"; see: "How much you like?"

John: I can't come over until I've finished painting my fence.
Mary: How much you lack?
John: I'm nearly done. I have about 30 minutes left.

Proof by lack of evidence 

The proof by lack of evidence fallacy is claiming something is true simply because nobody has yet given any evidence to the contrary.

Torturer: You are a heretic! You can't prove that you aren't one, so you are a heratic. Confess, or we will stretch your body out until you are a foot taller.

Accused: Ha, you did it - you committed the proof by lack of evidence fallacy!

Torturer: That's enough out of you. Brutus, give the wheel another turn.
