I know it is pretty complex the idea of "knowing words"; nevertheless, I would greatly appreciate if you people could show to me any chart on the "expected" amount of words learned / time of exposure to English. 

Like, a beginner level students, after, say, a term studying the lgg in a 100-hour immersion program should know (spelling, usage, adequacy, pronunciation etc) "x" words... do you know what I mean. 

There must be here on this site, sth. developed by Ricardo and his team, but I still haven`t found it...

Would you please give me some feedback on this?
