Those calculations are very interesting, but you'll find that well, for me normally - after building 4 of a facility - I then always build a Mineral Extraction, or Rad. Collider, or Eco Farm, or Robatoid Fact. etc. etc.

This is because at highest tech these produce more then building another resource prod. facility. Then anything built after that gets a further bonus.

I also destroy 6 of my starting facilities on large, or huge planets to make way for 1) a Robatoid Factory, 2) Urban Pacification 3) More Radioactive Refineries 4) Some other useful facility (Sys Robatoid, System Shielding, Resource Converter)

Okay, this may only be possible for high tech games, butit illustrates the point that it can be a lot quicker than 35 turns till you get ya money's worth back off these monoliths.

Maybe I'll do some excel calcs as well if it doesn't crash on me. . .
