> In other words, you can consider two hypothetical futures for a company: one with a specific person and one without that person. You then have a probability distribution defined over the difference in outcomes. For someone at a very high level, the absolute area under this curve is large—they have a big impact on the company (whether positive or negative). For someone at a lower level, their impact is small. Sounds a bit like the concept of "wins above replacement" as a baseball stat (https://www.mlb.com/glossary/advanced-stats/wins-above-replacement https://www.mlb.com/glossary/advanced-stats/wins-above-repla...), which attempts to calculate how many fewer (or more, in the case of negative value players) a team would have if instead of a given player, they had someone producing the exact average of the league.
