Is that the actual figure though?

TBF even that would be quite useful for lots of things seeing as it's faster than the DSL service I once had. However agreed that it isn't going to replace fiber service and overbuilding to such an extent for outliers would be absurd.

Still, that's quite decent considering it's an estimate of a near worst case scenario.
