24 teams play 154 game schedule
subleague A contains 2 divisions, 8 teams each
subleague B contains 1 division of 8 teams.

No interleague play, no inter-divisional play.

balanced schedule
3 game series

game time: earliest 1330hrs, latest 1930hrs
MON-THR prefer 1930hrs start
FRI-SAT earlier starts ok, doubleheaders ok

Sunday is mandatory off day

5 week springtraining
early April start
midway allstar game, with 4 days off for ASW (ASG is day 3 of ASW)

Should someone decide to take this on, many thanks !

The big picture is clear, but I would like some feedback toward working out the exact details.

The main thing is that 154 games cannot work out to exclusively 3-game series. So how to make it work? There are several possibilities that will work in different ways.

154 games divided by 7 opponents could be exactly 22 per opponent, which could be 11 home and 11 away. An easy way to get to 11 games is three 3-game series plus one 2-game series. The problem with this is that is creates a large number of series and unless there is some weird packing of games and use of doubleheaders there would be numerous weeks with only 5 games such that the schedule would run well into October.

The 22 could be split in some cases 10H/12A and 12H/10A for pairs of opponents. In those cases the 12s would be four 3-game series, and the 10s would be two 3-game series plus one 4-game series that could be accommodated by having doubleheaders. There would probably be no offdays except for Sundays and the All-Star break, but then the schedule could fit within 6 months.

If you are not absolutely tied to 154 games, then 156 works with only 3-game series. The balance would not be exact - the 156 works out with 21 games against four opponents and 24 games against the other three opponents. The length would be reasonable here, between the other two options, ending in early October.

So these summarize, these options are...
* Perfect balance, but long
* Balanced total games, but not in home/away for each opponent
* All 3-game series, but not same number of games against each opponent
...making the question what you see as important and/or what downside you most want to avoid.

Wow. Am speechless.

To address your points:

- am not wed to 154 games, and would like season to end early Oct at the latest.

- what I foresaw would be the use of doubleheaders on FRI and SAT, when need be to achieve some balance and get the games in.

- am wondering if having one day off / week is likely a problem as I play with normal injuries and very high fatigue.

**

in short - 156 games works, if you'd prefer to avoid doubleheaders. I don't mind them but also don't need them. Early OCT finish (reg season). What about staggering weeks containing more off days besides SUN? That might add an interesting component to managing through a particular dense schedule to get to a more restful week. I actually prefer schedules that aren't pristine. Having imperfect balances and variances in off days adds personality.

Also wondering how easy would it be for you to build up a few seasons which could be interchanged subsequently, so that over the course of a few seasons the games per opponent would be balanced? If it's too much forget it. Much appreciated !

Honestly I expected the perfect balance of 11H/11A times 7 opponents for 154 total games to be choice since I feel like requests more often go that way. Sounds like you are interested in that over the long term, but not necessarily in the one season.

I will work on the 156-game with all 3-game series. That makes doubleheaders unnecessary if everybody always plays series Mon-Wed and Thu-Sat. But some Thu offdays could also be sprinkled in by using that game as part of a doubleheader on Fri or Sat. My first thought is having one and maybe occasionally two of the four weekend series for each division do that each week.

The multiple season balance I think would take seven versions, and I think I know how to make the rotation work for that easily enough.

This is great !

11 x 11 is good, but went too late into Oct. Am playing with post-season tournament idea, so prefer earlier season end.

But I like the 156 g season flexibility - each of these adds to it

Attached zip has 8 sibling files that rotate through matchups so across whole set each opponent is played same number of times.

Code:

#
# 24 team schedule, 156 games
# Designed for the following configuration:
# 2 subleagues,
#     first with 2 division of 8 teams, and 
#     second with 1 division of 8 teams
#
#
# 21 or 24 games against 7 other teams in division (9-12H/9-12A)
# no interdivision games
# no interleague games
#
# Three divisions are copies of each other
#
# All games are in 3-game series
# One series each week is Mon-Wed, and one series each week is Thu-Sat,
# except some case of Thu offday with doubleheader Fri or Sat
# Sunday is offday for all teams
#
# Generally one doubleheader per week per division, but occasionally two or none
# Each team plays six doubleheaders in the season
#
# All game times for Mon-Thu games are 7:30pm
# Non-doubleheader Fri-Sat games any of 1:30, 2:30, 3:30, 4:30, 5:30, 6:30, 7:30
# Doubleheader game times 2:00pm & 7:00pm
#
# Season begins first Thursday of April
# Season ends first Saturday on or after Oct2
# Season spans 185 days
#
# All-Star Game first Tuesday on or after July 6 (day 97)
#
# Built 2023-07-22

Wow. Thanks for the work, gmo ! I will likely be adding a fourth, 8 team division a few game decades from now. So perhaps I could get these expanded to accommodate ?
