Back in the 90s I attended an anime club where the main host had an amiga with genloc to generate subtitles, and we watched all the anime classics up to that era. The host had a basic understanding of Japanese while not being fluent, but it was good enough that he'd download and retime fansubs. He also funded his own translations with a couple local exchange students.

Even with stuff at this hobby/mature level, the difference in someone actually taking care with the subtitles is not even close to subtle. It makes a huge difference.
