[time-nuts] are any time-nuts also random-nuts?

[Jean-Louis Oneto]

I'm not sure there is nothing behind the remark that the sum is somewhat 
"average": a long time ago (1973...) I used sum (or rather average) of 
uniform PRN to generate gaussian PRN. I think it described either in The Art 
of Computer Programming - Semi-numerical algorithms (Knuth), and may be also 
in Numerical Recipes.
I didn't check if the standard deviation for 6 values in [1, 49] is 
consistent with the range used by your friend.
FWIW,
Jean-Louis
