Most of Mary's physical symptoms (headache, asthma, dyslexia) were gone, but her intellectual capacity varied from day to day. I estimated a difference of 30 IQ points between crest and trough. I was determined to give her those extra 30 IQ points. Since John was already on the Failsafe diet, we put Mary on it as well. She didn't like the additional restrictions, but there it is.
Summer is the perfect time to perform this experiment. We asked Mary to do a little school work every day, about an hour's worth (which isn't a bad idea in any case). Each day we tracked her scholastic abilities. Thus we had immediate real-time feedback, just as we did with John (through his behavior). Let's find out what is really going on, once and for all, with both these children.
NFF: Unfortunately we didn't see much improvement, and we didn't get any hard data from these experiments.
