Must be working on the Pareto principle

"In the late 1800s, economist and avid gardener Vilfredo Pareto established that 80% of the land in Italy was owned by 20% of the population. While gardening he later observed that 20% of the peapods in his garden yielded 80% of the peas that were harvested. And thus was born a theory that has stood the test of time and scrutiny. The Pareto Principle or the 80:20 Rule has proven its validity in a number of other areas."
