When I started this thread I was listening to a few Spanish podcasts here and there, and watching a bit of Pepper Pig. What the million sentences target (albeit arbitrarily picked from a round base 10 number) did for me was changed my mindset. I moved from thinking a little bit of input would introduce me to everything there is to know to realising that I would need a lot, a hell of a lot. Especially if I didn't want to learn grammar from a grammar book (as I didn't and still don't).
I learn languages because I love doing so. Most people here are the same. So sure I do enjoy the process, but giving something to aim for whether it be sentences, flash cards, books, grammar exercises, or whatever else, can bring the results one desires and increase the enjoyment along the way.
Regarding whether the actual target of one million was a good one, I still believe it was a good choice both for me and for the video in the OP, despite dubious claims about possibly non-existent studies. Obviously improvement varies from person to person and from language to language, but they rarely vary by an order of magnitude.
I have nothing against a target of a million sentences for learning a language. If that is what it takes to motivate you, go for it. Of if you estimate that this is what it took to achieve a certain level, I can't disagree.
I gather that we are talking about mastering written and oral comprehension. I don't see any mention of written or oral production. How many sentences would be required to achieve mastery in speaking a language?
Let's take Spanish that I know a bit about. In my mind, mastering spoken Spanish means that you can have a conversation about a given topic with a native speaker. The conversation is at nearly native level in terms of content and form. Sure, you still have a foreign accent but what you say is interesting, engaging and not obscured by any grammatical or vocabulary issues. In other words, language is no longer a barrier. You are not a native speaker, but talking with you is interesting and informative.
How many Spanish sentences are required to get there? Sentences of what? Listening, reading, speaking? What about formal grammar study? Yes or no? How many hours of tutoring, if any?
As old-timers around here know, I believe in quality rather than quantity. Reading one 400-page book in Spanish about twice, including reading entire pages aloud to on-line tutors, did it for me. That one book contained nearly all the Spanish grammar and a huge chunk of the vocabulary that I ever needed. All the reading afterwards gave me more vocabulary.
Similarly, one telenovela that I studied in detail took my oral comprehension to another level. And then of course working with a tutor or conversation partner took my speaking skills over the top.
Can I estimate how many sentences were required for me to arrive at a given level? As I said before, I think the question is irrelevant - actually I was less polite. It just takes what it takes.
