Vilfredo Pareto (1848 - 1923) contributed widely in the general areas of Microeconomics and Socioeconomics. He is best known for the introduction of the Pareto Principle when he observed that 80% of the land in Italy was owned by 20% of the population. Also known as the 80/20 rule, the Pareto Principle becomes valuable in many lines of inquiry. In Trap Shooting, it is sometimes observed that 80% of the missed targets occur on 20% of the stations. In other words, right handed trap shooters miss most of their targets on station 5. Looking at the pie chart below, it is clear that if the blue slice represents broken birds and the red slice represents lost birds, then by improving on your weakest link (and therefore shrinking the size of the red slice), you can improve your scores most quickly and with least effort.
The value of the Pareto Principle is as a flashing bold red arrow pointing those weak links in our success chain. In the example above, the 80/20 rule coaches us that shooting drills on station 5 will be the most efficient way to increase our overall score.
