Is that 10:1 ratio post or pre-digital films? Because in my experience as a young PA film cameras didn't have live viewfinders. Film was maybe 2:1 or 3:1 because you didn't have unlimited film and unlimited film processing budget. Digital and reality TV has made it normal to film everything in multiple takes and clean it in post. But old school DPs, who were used to film, would get the whole thing done in one take without a lot of waste.

I heard the 10:1 ratio a while ago, and for "Hollywood films". So I'm guessing on-film, but where film/processing budget isn't much of a limiting factor. Primer was released in 2004 so at that time most things would have been on film.

That said, I'm not in the industry, this is just what I've read about the production of Primer, so if your experience was of 2-3:1 that may be more accurate!
