Not true.  There is NO bell curve.

What you are saying is that if you rolled die a bunch of times, you
would tend to get a 3 which is ludicrous.

Now what *is* true is that the average location of the key found (after
numerous runs) will be at the middle, but this is the same as saying
the average of the numbers 0-10 is 5.  It means nothing.
