You're right. That shows how often I have built the thing.
Hence why I included the caveat -
I wouldn't tech Robotics unnecessarily, but on the final turns of a space race everything is done and you're just killing time. This is when you build the Space Elevator out of sheer boredom so that the game ends one turn sooner.
That caveat fails though, because the assumption that you have ALL the techs in the game before completing the ship is somewhat ridiculous. If you're trying to actually end the game sooner, you research the technologies you need first. I showed that even a very dismal hammer empire can build the last ship part in 10 normal speed turn or less usually, which means even if robotics is the first thing you tech after researching techs you *actually need*, you would have to research robotics, build space elevator, and do so before your part completes + soon enough that it affects construction speed.
Not likely.
I think that Elevator becomes more useful if you are Industrious & going to win Space Race in a One City Challenge)
How many turns does it take you to research robotics?
How many turns after researching your final space ship tech do you need to complete the space part?
If the latter is < than the former, self-researching robotics and thus the space elevator loses instantly.
However, even if you get it from internet somehow, in OCC you have to ACTUALLY STOP building space parts while building the elevator, so in addition to the research time, you have to factor in the the delay ----> payback time of SE.
OCC setups usually have a LOT of base hammers. 100ish base hammers should be very common/expected, since you can just spam caste workshops, railroad mines, etc and have settled specs. If you manage that, even w/o aluminum or say iron you have 100% (factory + power), 50% (bureaucracy), 50% (lab), 50% (Ironworks 1 resource). A very awful situation for OCC gives you about 250 hammers...you can build an engine in 6-7 turns...you don't need the hammers as badly as you need the techs to build the parts, EVEN THERE.
