There's probably half a dozen errors in here, but it looks like the Mets end up finishing with an overall record that trailed only the Astro, Giant, and Nat organizations. Some philosophical ambiguity exists in the standings, as the wide divergence in the total number of games played leaves some teams behind others in the GB column despite having a slightly better winning percentage.
I left out the DSL and VSL because too many teams stock multiple squads, and would have a much better record if they had only one team.
