Rob, Intersting questions, thanks for bringing them up. One thing that occured to me...do you have a copy of Whispering in the Wind? If you do you can apply the New Code Change Format with your representation of "modelling photographic memory" as the context. Apply the Alphabet Game to elict a high performance state which will kick in the next time you model photographic memory. Model and let us know what happens. I am presupposing that you will model in the sense of modelling described in Whispering (suspension of f2 filters until criterion is reached) and that you will apply the other distinctions embedded in the book (for example, the differences between a statistical and discrete model).
