I wrote a couple of method review posts when I started:
A year of Greek, Dec 2014: http://discourse.textkit.com/t/a-year-of-greek/13117/2

I would do things differently now, and have a wider set of tools for language learning. But it’s fair to say that reading for the gist of things was my primary tool for a number of years, and I think that it has a lot of advantages. No one else seems to like to play in the Random Greek Passages thread with me, so it’s hard to level-set, but it may be that I’ve gotten all right at context guessing because of spending so much time at it. And I’ve had a lot of fun over 8 (!) years now of learning Greek. Your having 2 hours a day for reading makes me envious though. That has rarely been true for me since kids came along.
