You probably need to average something like 10x the big blind to make it profitable maybe a little more b/c sometimes your sets will go up in flames set over set etc. I wouldn't worry about times where you didn't make 7.5 BB b/c you will run into situations quite frequently where you make almost 100BB with your opponent basically drawing dead. The distribution looks something like this (3.5, 10, 25, -100, 100, 100, 6, 4, 15, -60). I wouldn't worry about once but if it happens consistently (e.g. your average after 400 sets is less than 8 )you may want to consider folding small pocket pairs. Low limit NL this consideration really isn't that likely. Higher Stakes short handed is where I started to encounter this problem.
