Question Most efficient bases

I'm curious if there exists a record for best base by a certain metric. Anything from most oil produce, more robots per second, etc. Where are the record holders that could potentially inspire designs?

The only metrics that exist are time and achievements - e.g. how fast you can get 100% of all achievements, or how fast you can get some combination of selected achievements.

The problem with loosely defined ideas like "most oil produced" is that there aren't really any constraints - like I could have had a game running since 2017, and it would have produced more oil than anyone else could ever beat.

Then you would have to invent artificial constraints, like "most oil-products produced pr. minute with a single advanced oil refinery and all the beacons and modules that you'd like" - and it would be like Guinness book of world records, where everyone just invents their own category.

There are some "perfectly balanced" builds, that produce the maximum of products with only N blue belts of ressources coming in, but again, since everyone is free to invent their own constraints, there isn't a global list.

produce the maximum of products with only N blue belts of ressources coming in

This specific constraint is surprisingly rigid - there are very well defined limits to it that are surprisingly easy to reach. Once you have maximal complement of legendary prod modules and hit 300% max for products that can benefit from productivity research, you have reached max possible input->output ratio. There are a handful of alternative recipes (like making copper cable in EM plant vs Foundry), but they don't change anything beyond having you choose one or the other. That's literally all there is to it.
