It isn't like the Nunn test itself doesn't skew results, remember.  IE the
opening book of the engine is eliminated, which means all the book learning
of the engine is eliminated. Now other forms of learning are eliminated.  This
doesn't exactly sound like a "useful test".  IE would it be interesting to take
two automobiles, remove one spark plug from each, drain the transmission on
both cars... (wait, one car doesn't have a transmission, just a direct drive,
oh well, drain the other)  and so forth.

I find that _really_ interesting to watch, and _really_ informative.  And about
as useful as taking the two PCs to your front porch, throwing them as far as you
can, and declaring the one that went the farthest "the winner".
