Obscure, unintuitive and unforgiving

bbq, one other thing to note is that you do not need to build 41 bases to make a sphere world. You only need 21.

And another 20 space station shipyards to build each stellar manipulation starbase.

At least that's how I do it, maybe people send in a dozen or so mobile space yard ships that were building stuff else where previously ... or they have a few stations build several several starbases. but ... for me, 41 bases + one mobile shipyard ... yeah ... seems about right at the end of the day just before the construct button is pressed.
