I feel like the days where we could joke on NANOG and say unhelpful things like, "Well, I start the bidding at 1%" and someone immediately follows on with an equally ridiculous "100%" and everyone agrees with 50% are behind us... alas.
Assuming you are talking about service providers and not their enterprise customers, you can probably get a fairly decent number by looking at routing announcements for whatever you'd call a typical network. Say...
AS (vendor L) routes / total routes or AS (vendor V) / total routes.
Since you are just looking for a percentage, and at that rate, I'm guessing 1 significant figure is sufficient, the number you pick for total routes > 230,000 will only shift your results slightly. As far as the numerator goes, depending on (de)aggregation, the number up top will probably fall in "bands" based on which networks you pick.
Enterprises definitely fall in bands first ordered by level of clue, and then by institution size within that "clue band".
P.S. I think that might be the first reference to "clue band", but I could be without a clue. ;)
