Tons of software did this for the longest time. Lookup tables have been a staple of home computing for as long as home computers have existed.
And CPUs still do it to this day. Nasty, nasty maths involved in figuring out an optimal combination between lookup table size and refinement calculations because that output can't be approximate, it has to work how IEEE floats are supposed to work. Pure numerology.
I really like reading people talk about how better programmers in a more civilized age could do things.
Anyone who has ever had to maintain old code will tell you that this more civilized age is right now and that the past was a dark and terrible time.
Seriously, there were no standards, there was barely any documentation even in large organizations and people did things all the time that would get you fired on the spot today. Sure, you had the occasional wunderkind performing amazing feats on hardware that had no business of running these things, but this was not the norm.
I didn't have to maintain it, actually I haven't ever worked as a programmer. But I've patched a few FOSS things abandoned around 15-25 years before that to work as a hobby activity, some kind of digital archeology.
I think people also do things now for which they'd be fired on the spot 20 years ago. Everything changes.
I suspect what you call "no standards" means in fact "different standards", but that's just a cultural difference. Some project from 1995 may use "Hungarian notation" in variable names, well, that was normal then.
That adequate version control and documentation are, eh, a bit more of a norm now, - yes.
