I think this picture only makes sense after you have done the route. The route finding is pretty straightforward with the written description. It does get a little tricky on P6 & P7. On P6 you need to head up to the roof and cut across a ledge system. We went to the arete before hitting the roof. On P7, you just need to keep a eye open for the sparse bolts.
Just now saw the comments - I posted this for the benefit of folks who plan to rap the route to get to the base. If you didn't know where to look at all, you might have trouble finding the anchor locations from the top down.... It is a little trippy, though.
