2S/5D/4T, 162 games with interleague
 

Nothing too crazy in this schedule, aside from some unusual interleague placement.


I tried to make this one myself, but hit a snag because of the odd number of divisions not working with my usual scheduling structure.



# 40 team schedule, 162 games
# Designed for the following configuration:

# 2 subleagues, each with 5 divisions, each with 4 teams
#
# 14 games against each of 3 division opponents (7H/7A, 4 series per, 12 total series)
# 6 games against each of 16 non-division opponents (3H/3A, 2 series per, 32 total series)
# 3 games against each of 4 teams in the corresponding division of the other subleague (3H or 3A, 4 total series)
# 3 games against each of 4 teams with the same position in the non-corresponding divisions of the other subleague (3H or 3A, 4 total series)
#
# Season starts first Tuesday on or after April 1
# All-Star Game on first Tuesday on or after July 15 (day 106)
# Season ends first Wednesday on or after October 1
# 184 days; 52 total series + All-Star Break
#
# Interleague played in two 4-series blocks
# Corresponding-division block starts on a Friday in mid-May
# Non-corresponding-division block starts on a Friday in mid-August
#
# All game times set at 7:05pm

Maybe I can give a helpful hint. For the interdivision games, rather than treating each subleague as 5 divisions of 4 teams, split up each division and treat it as though there are 10 "half-divisions" of 2 teams.

Then you have an even number of "half-divisions" to allow for everybody in the league to have an interdivision matchup at the same time. Just make sure to exclude the divisional matchups from getting into those "half-divisions" matchups.

Here is an example of splitting each division into half-divisions "A" and "B"...
Each half-division matches up there once against each other half-division outside its division. (Maybe double-check my work to make sure)

The upper-left pod of "2A 1A" corresponds to four games since 1A encompasses teams 1 & 2 and 2A encompasses teams 5 & 6...

I'm well aware of that trick, having used it myself in the past. I wasn't able to make it work in this specific case.

I'll retry at some point today.

I did work on this on the weekend but did not wrap it up then. Below are the results, one fitting in the same shape as the 2019 MLB calendar and one fitting (I hope) the prescribed parameters.

Thanks. I'll take a look at these schedules tonight. Should work well with what I'm planning.

In the Tuesday-start schedule, I noticed a five-series homestand around the All-Star Break; didn't look at every team, so there may also be a five-series road trip for one of them.

Yeah, I have gotten a little lazy. I am generally relaxing the "consecutive series where" count by allowing the All-Star break to count as breaking the streak. I.e., the break counts as ending a homestand or roadtrip.

So I am trying to be careful (though probably not perfect) with the comments in that case and say something to the effect of the constraint being on the length of the homestands/roadtrips and not strictly "consecutive games played" home/away.
