A100468

[franktaw at netscape.net]

As n gets larger, the average number of digits in the decimal expansion 
of 1/n grows fairly steadily.  The number of digits in n takes a jump 
at powers of ten.  So the density of members of A100468 grows steadily 
until a new power of ten is reached, when in takes an abrupt drop.  
That explains the main features of the graph.

There is some smaller level detail, which I can't immediately see a 
reason for; but this also seems to be associated with a(n) being a 
round number

   Could someone give me independent verification on my b-file for this 
sequence?

 Otherwise, any explanations for the graph?
