Yeah. That sums it up.
In my experience, it comes down to riding style and event focus and less about height.
For example, bike check interviews have had Sarah Hammer on 172.5mm cranks and Jamie Staff on 165mm cranks.
Crank length is important for unlocking that last 10% or so of power and speed. The thing is, you may have already lucked-up and started with your optimal crank length...you just have to experiment.
