maybe, maybe not, but of course the last 10% isnt just vaillages, the first 30% of BTs FTTC rollout was mainly rural areas.
When people refer to the "last 10%" in this context, they usually mean the "least likely 10% to be included". It also means they're going to be the last ones physically worked on... because they won't get worked on.
But the reverse isn't true.
In a large rollout, the first 30% of the rollout in time
that BT happen to actually work on, don't have to be the first 30% in terms of likelihood of service, or profitability, or priority. They probably happened to be the easiest to run the project on - either because of the ease of civils, the space in the exchange, or the ease of using the manpower.
However, the "last 10%" is almost certainly still going to be the least dense, longest backhaul cases.
EO's are a special case that don't quite fit right - they're probably dense enough, and have short backhaul (certainly reasonable backhaul). However, they have an excessive build cost for a different reason.
My gut feel is that most EO lines that go in "bundles", while not cost-effective during commercial deployment, will prove to be OK for BDUK funding.
But it is no more than a gut feel.
