Distinguishing between RRN types in queries

Hello, there. I’m learning about LEQL, and observing results when I try different queries. I noticed that there are two columns: r7_context.destination_user.rrn and r7_context.destination_account.rrn

It seems that a user will have one of each type. When would a search benefit from doing RRN searches which pertain to user, and in what cases would the RRN for account be used?

I’m curious because my documentation tends to be exhaustive, describing a case-by-case comparison, especially with the uniqueness of RRNs

If there are better tools, I’d love to hear about them!
