What an interesting site! Thank you for the link. As you note, much of the content is relevant to any sort of depth psychology.
I've gone back and forth on this issue in my own mind over the years but, in the end, I rarely determined how long. For the most part people in my practice fell into two clusters- one the problem solving oriented and the other the more introspective who found it helpful to take time out on a regularly scheduled basis to work on long term patterns of
behavior that interfered with comfortable living. That being said, I personally always fell to the side of life is problematic so deal with it- I was more inclined to be the reluctant patient. 
Being analytically inclined albeit not an analyst, it has been easier for me to live pretty comfortably with people taking as long as they take. Some folks, as you say, are problem oriented and once the problem is solved, feel no further desire to continue with therapy while others find long term work rewarding and challenging. Personally I fall into the latter group.
I'd love to be able to go long term. Early this year, though, I had to go from once a week, to once a month, as my church had been paying for my therapy, but the (lay) clergy changed (well, they switched boundaries for the congregations, and we are in a different one) and I'm afraid of bringing it up. My ins. only covers 20 visits a year, so we're stretching them out until I can figure out something . . . . I work as hard as I can, but there is so much going on that yanks and skews things inside, I work and fight. I need help to sort things through, to have a healthy perspective from an understanding, accepting, and therapeutic source. Plus, I'd love to be able to delve more into why I am the way I am, and work through various things, deep things, and I've done some deep things in therapy, but much of it is necessarily more about stabilizing, managing or trying to daily overwhelming stuff, etc.
I just wish there was some way . . . . I want to figure myself out; wanting to know the WHY has been a deep burning inside me since I was a child, a very intelligent one, knowing I was "off" with the way the world works, the way people cope, think, interact, but not knowing what or how, and hurting deeply each time I scraped up awkwardly against this in my different, not knowing how to be or do any differently than the best I could figure out, way.
Sorry to go on and on! Anyway, I found this post interesting, enlightening, and full of points to ponder.
