If 4 out of 162 games lead to a 30 point swing, the system is flawed
It's a question of between who were those 4 games, at what point in the season, and with what looking forward. 4 games between the two players in a two-team race, at the beginning of August, with the Mets heavily favored going forward based on schedule.
The Nats pissed away too many of their easy games already. April is hurting more and more, and those sweeps in May that weren't, when the Nats would find a way to lose a game and instead come away with 2 out of 3, those losses are hurting too. And then, of course, 5 games lost to the miserable Reds.
But I have no idea how the system works, I'm just guessing here.
