What are your thoughts on (and, preferably, experience with) a set of 
tests that people can use to assess the consequences of changes in 
diet, exercise, sleep, time of day, nootropics, age, etc. on 
cognitive functions?

The tests need to:

a)  cover a reasonable range of abilities
b)  take 5 or 10 minutes to complete
c)  cost under $100
d)  retain accuracy across dozens or hundreds of uses
e)  can be used alone, at home or when travelling

For example, an easily created subtest might present a random 
sequence of digits, on screen or spoken, to be repeated or reversed. 
Unfortunately, requirement (d) isn't so easy to meet for other sorts of tests.
