And even that is only recall from short term memory (reading out lout and then immediately writing it down without looking at the source texts). I guess it's not really the same as actively recalling vocabulary after long periods of time, and I'm afraid it's not the most effective and efficient technique...
Kaufmann's method is even more passive than Arguelles'. But keep in mind that he didn't use it to learn the languages that made him famous. He used "normal" techniques to learn Mandarin and Japanese when he was younger. He used a lot of active recall back then. The language learning that he did after he started his website is not as remarkable as his earlier learning. And even with those, he eventually did a lot of production, which requires active recall, so it's hard to credit his way of starting a language passively for everything.
Yes, and French he learnt inter alia in France where he studied, Swedish as a kid, and for his other languages, he says himself he has not reached a C-level in any of them.
