This version from Buffet starts to hit on a piece of the original Ted Williams version that might not be apparent for non-baseball fans.
Williams is measuring batting average which is the number of hits divided by the number of at bats. Hits come on a single pitch but at bats are a collection of pitches. Therefore a pitch location for an at bat isn't really something that makes sense. This ends up biasing the results.
You see the pitches in the middle of the zone are not just red because it is easier to hit balls in that location, although that is certainly part of it. Another factor is how those pitches fit into an overall at bat. Pitches aren't thrown at random parts of the zone. There is a strategy to when they are thrown in what location. Pitchers will often only intentionally throw the ball in the middle of the zone when they are behind in the count and are trying not to walk the batter. The batter know this so he is able to anticipate pitches in the center of the zone when he has the advantage. By ignoring balls thrown to his weaker areas, he often is able to get ahead of the pitcher which creates a multiplier and allows him to hit the ball even better when it is in those locations in which he already excels.
Knowing his weaknesses allowed Williams to minimize the situations in which those weaknesses would come into play. That allows him to focus on his strengths and actually increase the number of opportunities that he had to act on those strengths. It is the equivalent of Buffett benefiting from compound interest that gives him more capital to invest the more successful his investments are.
