Work crux sequences from the top

Projecting a route often means you start doing and then linking the hardest moves. If we are talking long crux sequences that you can not get together a good strategy is often to start from the last hard move. How should you place your hands and feet in order to do the last crux move? Once you have dialed this, you can work your way down how to reach the exact position in order to do the next hard move etc.

One dilemma by instead, and which is more natural from the beginning, work your way from below, is that you will fail more often doing the moves which could create a bad mental state. Furthermore, as you will try different solutions you will not get that power boost by doing and recruiting your muscles by repeating the exact same move. Lastly, starting from the bottom of means you will do longer sequences before you fail, and thus, will get more tired in comparison if you just work your way doing one move at the time.
