I have a system I use that determines my tip:

20+%: A meal where the wait staff went above and beyond to make my meal an enjoyable experience.
18%: My standard tip. An overall pleasant meal with no issues.
14-16%: A few minor problems, but no major ones. Maybe the wait staff took a long time to refill drinks (obviously with allowances for if the place is super busy) or was acting like they didn't really care about doing a decent job. Enough for me to notice, but not really enough for me to complain or seriously deduct from the tip.
8-12%: Some definite problems here. Unpleasant or rude wait staff, food that is of poor quality, or something else that generally made the meal unlikable. Usually if I leave a tip like this I'm not returning to the restaurant for a few months afterwards, as it suggests that the place probably has some issues in how it is run.
0%: A complete disaster with absolutely no redeeming qualities whatsoever, with both food and service being severe disappointments. If I leave this tip, I don't come back to the restaurant ever unless it changes ownership.

I've only left a 0% tip twice, and both times thoroughly earned it. One of them, for instance, was at a university bar and grill. We were a group of five people and we were one of just three tables in the place that night - it took an hour and a half for our food to arrive (and when it did it was cold) and in that time the waitress only refilled our drinks once (and whenever she came by the table, she acted like we were distracting her from doing something more important).
