He then goes on to describe other benchmarks you might go for. But the minimum bar he's advocating is very low compared to what I think most people would expect.
I've had much better luck with this system than with what I was forced to use in school to learn French, which was basically slowly build up all of the skills at once(learn a little grammar, a few words, at a time).
* learn pronunciation/spelling first
* learn the top words using images and space repetition
* study every single day
I think this method is by far superior to anything taught in high schools in the US, which is very sad given a large portion of our population speaks Spanish and I think they could change the curriculum a bit an a lot more students would leave school bi-lingual
