here is the referance graph:

In this graph, retention is currently being calculated based on the next day, but I want to analyze it based on the previous day instead.

Example:

For July 27, we should compare retention against July 26, not July 28.

• So for 1-day retention on July 27, we should look at users who were active on July 26 and returned on July 27.

• Similarly, for 7-day retention, we’d check if users who were active on July 20 returned at any time between July 21 and July 27.
