I don't think anyone else can help you determine your estimaation...

4/8 was originally BBN. Anycasted DNS resolvers came to many networks 
somewhen 98-00 [I can't be more precise as my archive of 1994-2007
work and events is naturally out of my reach, being that employer's 
data].  But I seem to recall that was Rodeny's babye form the Genuity
days.

That is a question for folks at L3.  Any publicly-sharable data might 
be interesting presentation-fodder.

Why "conjecture"?  Examining the /32s from inside and outside of 3356
clearly shows the whole set still is, and those who have been customers
or worked with the 3356 folks over the years know it has historically
been as well.
