This report focuses on the performance by age group over a number of normed tests: Test of Shock and Awe, Short Test For Genius, Space, Time and Hyperspace, Bonsai Test, CIT Forms 1 and 2, Final Test, Analogies subtest of Long TFG, Association subtest of Long TFG, QMC #3 and #4, Genius Association Test, Numbers, Test For Genius Revision 2004 and Test To End All Tests.
For each test the average I.Q.s by age group are computed. For each age group the weighted average I.Q. over the tests is computed. The following table gives for each group the number of scores on which the average is based, the average I.Q., and a graphical representation wherein the number of *s is (I.Q. - 103)/3.
| Age group | # scores | I.Q. (SD=15) | Graph |

It is a pity there are no scores in 65-69 yet, as that is probably the point where the decline of old age starts; or does it only start in 70-74, and is 65-69 still relatively close to the ages 16 to 64, which form more or less a solid block? We will see later.
