I didn't notice their language about the whole 9.6 pts. thing. It wouldn't surprise me, the Reinert studies only go so far. The technique, in light of these facts, probably doesn't improve IQ much more than 8-10 points. Still substantial, but not the 50-100 points Wenger indicated was eminently reasonabloe to suspect. the quote about clark kent sounded "fruity" to me by the above definition.
