How does Treehouse calculate my next steps? What is the best way to calculate / setup a learning plan?

I notice when I login to the site (and also by email) I am getting some next steps for the day... how does treehouse calculate this? The recommended steps are a lot smaller and would lead to a much slower rate of course completion than I want to go.

I just signed up to treehouse on Saturday, my plan is to complete the web design, front end development, rails development, PHP development, starting a business, wordpress, wordpress development, learn ruby and full stack javascript tracks. I am planning on being pretty aggressive with my learning and then likely I will take some classes with code school and then do a nano degree with Udacity.

I am trying to set goals, timeframes etc for this, like a normal class schedule, I currently work 32 hours a week, so I am planning to do 3-4 hours each evening and on my two days off to do 8+ hours.

Is there any way to calculate the time to complete all these tracks, measure progress for my custom learning plan, estimate completion dates or seeing what I have to do to complete by a certain date?

If not it would certainly be awesome if Treehouse had this feature! Anyone attempted/attempting anything similar, use any other tools to track=monitor progress?

Namaste!
