As was noted, the Manticore home system had the highest per-capita GSP. It does not have the highest GSP. And one of the characteristics of the SKM in 1905 was fairly low taxes.
I'm going to agree with kzt here. The SKM had an economy comparable to the best Core System worlds and bigger than most of them. That it was in the Top 1% of all populated systems seems like a reasonable assumption.
That means by corollary that there were other systems with economies and populations that could have done the same. They just chose not to. And yes, it'll take them time to get there. Even if they had the shipyards ready to lay down the keel today, building an 8 MT SD is about a 36-month effort for most people and we're talking about building 150 of them.
It's totally doable. Some of those Core World systems must have been settled for over 1500 years, starting from an industrial level higher than ours today. They're probably way past Kardashev I scale, though I'll note that there seems to be no system that is even close to Kardashev II in the Honorverse -- even the SL itself as a polity may be called Kardashev II.
We don't know if Beowulf was the most prosperous Core System. It seems likely, but it's not a given. Sol definitely had a larger population and larger industrial base (at least until they got a certain visit recently). I wouldn't be surprised to find another Core System that had a population in the 50 billion mark and an industrial output comparable to two or three Beowulfs. That's peanuts in the time scale we're talking about. And mind you, you don't need a populated system to have an industry: find a nearby K-type star with sufficient asteroids, of which there are plenty, set up some auto factories and Von Neumann self-multiplying industries, and you can crank up ships by the thousands. It just seems, like the Kardsashev II scale, David doesn't want to go there. Too much like Dahak, I guess.
There's also the question of whether the crème de la crème of Core Systems will stay in the SL or not. If enough Core Systems leave, the SL crumbles. So I expect David will give us an independence rate around the 33% mark, enough to hurt, but not enough to be fatal.
