What is the ER of a choke knot?

ER, or efficiency rating, measures how much of the rope’s original breaking strength remains when tied into a knot. A choke knot tightens around the standing part and creates a constriction that concentrates stress, which significantly weakens the rope. The choke knot typically retains about half of the rope’s strength, so the ER is around 50%. That’s why 50% is the best answer. Higher values would overestimate the retained strength, and 95% would be unrealistically high for this knot.
