Btw, I wasn’t suggesting you to give up the people. I said that only to check if I had understood your method. Since the people don’t encode anything, their sole purpose is to make the images more memorable and distinct as you said here:
Yes, I got that.
I believe I understood your system, but it still doesn’t seem to be a 2-card system to me. I feel there’s a difference between people and locations. The sense of direction and position is implicit during memorization. During encoding, you don’t need to focus on where you are. You just go there once, and then you just “stay there.” When you review, you don’t pay attention to the location, just to the image in the locus. If it were a person, you’d need to focus on them through the entire process. You can read more on another discussion here.
Also, I feel like there would be a lot of training involved when compared to a normal memory palace. Our natural memory apprehends the places easily, but the images require more review. For instance, if you don’t practice, you’ll forget the images faster than the palace itself.
Lastly, if you were to do 1-hour cards, these images would repeat really many times, unless you make the people in each memory palace different, which means even more upfront training, so you would be better off getting a 2-card system from the start.
All that being said, I do think your idea works. Depending on your personal preferences, you may even like it more than a standard 2-card system. I just don’t think it’s as efficient as the shadow, Ben, or even the Double-2-Block system.
Btw, I remember Katiek said in the forum that she built a Ben System really fast, so I believe she uses it. I believe her memory palaces aren’t intended to substitute a 2-card system.
