Not surprisingly with the weekend approaching, your writer’s thoughts turn to golf. Every golfer who plays regularly should have a handicap index. This is probably the most misunderstood statistic that golfers use. The short explanation is that for every round one plays, you (or a computer, usually) figure out the stroke differential between what you shot and the stroke rating of the course. You adjust that for something called the slope rating (a measure of how difficult the course is relative to other courses) and add it on to your list. Your handicap index is 95% of the average of the ten best (lowest) adjusted stroke differentials of your last twenty rounds. Clear? Good, because it’s a great business lesson too.
