Jer,
I don't know if his examples are inline with a suggestion I made to you a while back but my thought was for Hal to be able to recall what he/she knows or has learned about me, my dog, my kids, etc.
The subject matter might be able to be organized into categories like persons, places, pets, favorite songs/music, poetry, art, etc.
Just some thoughts.
You're doing great work!
Thanks!!!
PS: Ever hear from Rob regarding your EFA??
