Why does this rope have a static and dynamic rating? Which one is it?
It is a dynamic rope. The static number is the % stretch you would likely see if you were top roping, or had asked your belayer for a take. The dynamic number is how much it will likely stretch in a lead fall. Hope that helps!
Static elongation = elongation under a static load. "Static" means you're not moving, so imagine you're just resting on the rope, dangling there. That's a static load. "Dynamic" means you're moving, so the dynamic elongation spec would apply in a lead fall.
