According to Malcom Gladwell, it takes 10,000 hours of practice to become world class at anything. I am just shooting for a one time impressive score for bragging rights. This will probably be less than 10,000 hours. Ergo, the new line on the graph. That new line will be the definitive data describing how long you must practice to be able to shoot your mouth off with some assurance that, in the right company, you will have a score the top 1% will be impressed with. I wonder what Gladwell's e-mail is...
