Yeah, that’s definitely wrong. Assuming 1.5 hours a day, I’m willing to bet it’s closer to 20-50 words per day depending on how you go about it, what language you are learning, and what level you are shooting for.
The point is that you learn and forget, learn and forget, learn and forget until you’re up to around 30,000 words (say an English speaker learning a Romance language to fluency).
