> a crude stack ranking by lines of code is a pretty good metric for figuring out which (e.g.) 50% is the bottom. I can write you an efficient algorithm in 2 lines or an inefficient one in 50. The metric is about as useful as a doctor checking how often someone picked up a bottle to figure out how much they drink.
