So, after consulting with Ken it appears offense simmed low over a full season on the eras for this year's database. Last year you may recall Dan Syzm sent out tweaked eras last year. I imported those eras into the database and the year will be played going forward with those eras - for now. Over the course of a season, the offense was closer to what it should be, but not perfect. DMB and Dan have been alerted to the problem, so hopefully there will be a better fix than that.
For now, this will do. We're all on the same page and same playing field, so there's no real advantage either way. The tweaked eras from last year play pretty close to how it should anyway, but not exact.
Results from opening day will stand. I don't want to waste people's h2h efforts and as I said, it's everybody on the same playing field.
