Parkouristx (Johnny, right?), unfortunately like I said I haven’t been able to memorize most of that stuff yet, so I’m not sure! You’re talking about adding additional bits of information, right? Like with the list of US presidents, for instance, you might also want to include their years, a few important events, etc.?
Right now what I’d try is just tack extra images onto the locus. If you really have a lot of information, I would use subjourneys. For instance, if Abraham Lincoln was on one locus, I’d have that locus be a “portal” into a separate journey. Kinda like Gavino’s massive memory palace stuff if you’ve read up on that. Or you could the image as a “mini-palace” in itself. Look at Bateman’s “Conversation B/W Newbie and Me” and search “mini-palace”:
Sorry, I can’t quite tell if you’re asking about how I’d do it or about how much detail I’d want 
If the latter’s what you meant, sorry for rambling! Like you said, it just depends on what you want. I think for most of the things in my list I wouldn’t memorize too much detail. For the purposes of these types of memorization, I personally think it’s better to know a little about a lot of things than the other way around.
