You seem to be referring to the shift from using "ratio IQ" (mental age divided by chronological age) to using "deviation IQ" (an expression of how far someone deviates from the average of 100). The third edition of the Stanford-Binet IQ test adopted deviation IQ scoring in 1960, well before the publication of the Monster Manual, or Blume's article for that matter, in 1977. But it is quite possible that Gygax was using outdated (at the time) IQ classification schemes as some kind of model for his chart in the Monster Manual. His use of the term 'genius' strongly suggests this, as the last IQ test to use this classification was the original 1916 Stanford-Binet IQ test, which classified a ratio IQ of above 140 as "'near' genius or genius". This translates into a deviation IQ score of above 136, thus my comment that, if you accept Gygax's use of the term 'genius' as referring to an IQ classification and see that is covers an Intelligence score range of 17 to 18, multiplying by 10 will produce a number for the lower end of the range (170) nearly 40 points (34 to be precise) off from where it should be.</p></blockquote><p></p>
