The way WAR is structured, A presumably won three extra games all by himself in April and again in July, while B won one extra game all by himself each month, and at the end of the season, they both won six games all on their own, which makes them equal. What I don’t know is whether there is a diminishing return, a marginal utility, at the top end of a player’s overachievement that’s baked into the WAR calculation. I’ve never seen anything on that topic.
