In the rule “Departments” add a subrule called “Index Correlation” with the following text:

Each Innie has a Guidance Index, privately tracked by the Board, which is a number that is at least 0 and defaults to 0. If they have not done so since the last Correlation Tally was performed (or since the beginning of the dynasty if a Correlation Tally has never been performed in this dynasty), an Innie in the Department of Index Correlation can set their Guidance Index.

The Performance Index is the mean of all Innies’ Evaluation Point, rounded down to the nearest integer.

Correlation Day is a date privately tracked by the Board that is September 10 2025 by default. If the current date is on or after the Correlation Day 00:00 UTC, at their earliest convenience the Board should perform the Correlation Tally, which is an atomic action with the following steps:
* If at least 50% (rounded down) of the Innies in the Department of Index Correlation have a Guidance Index that is non-zero, reduce the quota of the Department of Index Correlation by 1, to a minimum of 0.
* If all Innies in the Department of Index Correlation have a Guidance Index that is non-zero, reduce the quota of the Department of Index Correlation by 1, to a minimum of 0.
* For each Innie in the Department of Index Correlation that has a non-zero Guidance Index that is at least 2 less than the Performance Index and no greater than 2 more than the Performance Index, reduce the quota of the Department of Index Correlation by 1, to a minimum of 0.
* Set each Innie’s Guidance Index to 0.
* Privately randomly roll DICE3 + 2, and add the result in days to the Correlation Day.
* Make a blog post in the Story Post category indicating that a Correlation Tally has been performed.
