I understand your point, and well taken. Pertinacity is not my intent, but I will reword my question so that it becomes relative to yourself and whoever else might want to respond in here just so I can get some ball-park ideas.
If you personally went back in time to when you were a beginner and had the same goal, i.e. to read and write "well" within a year - by "well", I mean from a scale 1-20, a 12 or 15, where the 5th grader who just began studying Latin can read and write at a level 1 and St. Augustine of Hippo can read and write at a level 20 (or whoever else you might argue for the 20 mark) - how many hours, etc. a day would you dedicate "yourself" in order to reach that goal?
