Oh, I actually have no idea about the mobile version. Not sure what the capabilities are for that. For some reason never occurred to me. Maybe a question better in its forum.
As you describe is the layout. The 2-game series to conclude the first half span day numbers 86-91 and the second half 180-185.
The schedule does have All-Star Game defined, but HR Derby is set through League Settings > Options > All-Star Game Settings. Again, at least that is how the non-mobile version works.
You do have the understanding of the use of the numbers. That is how schedule files work (see
https://wiki.ootpdevelopments.com/in...OOTP/Schedules), using internal ID numbers instead of names. With numbers the file can work with any league with the corresponding configuration instead of being tied to particular team names.
