Thanks! It's actually not that crazy, for 10k effective SPM I didn't even build a larger base and still had 10 assemblers for red science, 12 for green, etc. - that all went with Beacons and quality and science productivity + improvements on the side of producing intermediates by using EM plants to make chips and furnaces to make gears/steel/etc.

Actually that part I was able to get a over 20k science and now I am building a larger science production bit with 4x of everything that I had before. Certainly larger in scope and I often have stacked green belts of stuff, but still hardly a megabase.

I saw people who are really pushing it are going way over 1million SPM in space age :O... but I'm also still quite casual and don't think about stuff like UPS and also don't copy build blueprints, so my builds won't be optimal at all.
