I actually found I like path better then old tree. The big difference is that with path, I do the next dot on the path or dont. With tree, I was tempted to constantly optimize the xp. Do I want 2x now or later? Should I do revision or new content? Should I continue this node or that node? When was the last time I did the boring node I am avoiding?

With path, there is no obsessing over strategy, pop up app do the lesson and that is it. I also found that I retain more, because revision is build into path instead of me having to manage it.
