A small correction has been to the very first schedule in this thread (
found here) which was for a 12-team league. The post was editted drastically, but the only change was getting rid of an accidental doubleheader between teams #8 & #11 in early May by moving one game to a common offday in mid-August.
The previous version still works if you have it, there just may be issues with the doubleheader.
