the second test reported by guinness was hoeflin's mega test, taken in the mid-1980s. the mega test yields iq standard scores obtained by multiplying the subject's normalized z-score, or the rarity of the raw test score, by a constant standard deviation, and adding the product to 100, with savant's raw score reported by hoeflin to be 46 out of a possible 48, with a 5.4 z-score, and a standard deviation of 16, arriving at a 186 iq. the mega test has been criticized by professional psychologists as improperly designed and scored, "nothing short of number pulverization".
