I have been at it for about six weeks, and have gotten 43% of the way through Guitar Fundamentals One. As Lisa says, every single person is different. Some things are quick for me (in my case I have a musical background), but some things, like actually PLAYING the guitar, come v-e-r-y s-l-o-w-l-y to me. For instance, just now I am learning Lisa's tune 'Darling Destination', and my progresss has slowed to a crawl, as I am not doing super well wirth cleanly changing from chord to chord all through the song. I don't intend to get as good at it as Lisa is before moving on to the next lesson, because that would slow me to a glacier pace, but I want to be in the ballpark, at least. It's so great that the videos can be slowed down and then gradually brought up to tempo-- a lifesaver!
