Every projection worth nothing should be changed after two games if the team performed a full game different than expectations. If a one-game swing isn't big enough to change your projection, what is? Two games? Four? I'm not sure why you'd draw the line higher than one game. On a similar note, Carlos Zambrano will have a hard time putting up another 120ish ERA+ season or an ERA under 4, just because of what he did on Monday.
