Question about the terminology

So I've gotten most of the terminology used on this forum but still have a question
For series like History's Number 1 Founder are the series under Related series
There are Adapted From and Same Franchise I'm assuming same franchise just means under the same author and is in no relation to the universe but how does that work with adapted series

 

because HN1F is a parody hence adapted from <...>

 

It's kind of like in film where you have "based on a true story" where writer's create a lot of leeway but the basic premise is of a shared serious.

 

Adapted from has a parody tag where a part of the story in another novel is used in the series which is going to be an important part of the main story. Same Franchise just means it has the same author.
