Interesting, not heard of the accelerated learning techniques before, but the theory of brain exercise certainly sounds feasible. I guess it's a case of how long you've been a mushroom (brain in dormant mode!) as to how long it will take to get it back up to speed. My six month figure was because that's how long all my grounschool course took, as I mentioned by the end it was certainly up to speed, but I had been running as a background task for several years!
