a more direct Scotty connection to “bucket of bolts” is the end of The Voyage Home - Sulu says he hopes the crew are posted to Excelsior and Scott incredulously dismisses it, his former posting, as a bucket of bolts.
also, we’ve seen humans on Vulcan in Amok Time, The Search For Spock, probably some Discovery, and none of them had any apparent difficulties with high gravity, Kirk could even fight, and you can bet Bones would have grumbled about it.
I would say it’s The Voyage Home that established warp 10 as the ultimate threshold, a few years before TNG.





PieFed did some policy change on… weighting votes for people who vote thousands of times a day, or something like that? PJ said that made him want to change instance again, but he’d done that a few times already and couldn’t be bothered with the process again. (this is from memory, i haven’t double checked while writing)
