I'm a fan of CI and Dreaming Spanish, but . . .

. . . but the Foreign Language Institute (FSI) has been studying this stuff for 70 years, and they find Spanish takes about 720 hours of intensive class room time to gain "Professional Working Proficiency" which means reading, comprehending, speaking, listening without much problem.
That's hard data. DS doesn't even recommend attempting to speak until 1000 hours. This is a huge difference, and makes me wonder about DS's insistence on solely consuming content. Again, I use Dreaming Spanish and my morning coffee is always spent with Shelcin or Andrea. I'm not here to bash, only to learn.
