James, if you are going to place long links here, it is best to use bit.ly or something to shorten them to make it easier for people to follow the link.
Re the substance of your comments, I suggest you read the post a little more carefully.
In my post I quote this definition of level 2 proficiency provided by the US Foreign Service Institute.
“Limited working proficiency. The person is able to satisfy routine social demands and limited work requirements.” I then call this “basic conversational fluency.” and comment as follows.
"If we are able to put in 10 hours a day, then basic fluency in the easy languages should take 48 days, and for difficult languages 72 days. Accounting for days off, this equates to two months or three months time. If you only put in 5 hours a day, it will take twice as long.
Is ten hours a day reasonable? It could be. Here is a sample day.
8-12: Alternate listening, reading and vocabulary review using LingQ, Anki or some other system.
12-2: rest, exercise, lunch, while listening to the language.
2-3: grammar review
4-5: talk via skype or with locals if in the country
7-10: relaxation in the language, movies, songs, or going out with friends in the language. depending on availability.
To some extent the language needs time to gestate and often things we study today do not click in for months. On the other hand intensity has its own benefits. I have no doubt that someone following this intense program, or something similar, would achieve basic conversational fluency in 2 months for easy languages, and 3 months for difficult languages.
To go from level 2 to level 4, or full professional fluency would take quite a bit longer, perhaps twice as long. This reminds me that I wrote something on this a few years ago. If I find it I will post it. "
So, to get back to my original comment here, most people are not going to put in 10 yours a day. Once we quality “fluency” , basic fluency, quite fluent, somewhat fluent, etc. we can have all kinds of gradations. If we say, I am fluent, without qualification, then the assumption is a high level of fluency, in my opinion. Most people will not achieve this in three months. That is what I said, and I stick with it.
