What is the ER of a clove hitch?

ER represents the efficiency rating of a knot—the fraction of the rope’s original breaking strength that remains when the knot is tied and loaded. The clove hitch secures the rope with a couple of bends and several contact points around the object, which creates stress concentrations and potential slipping under load. This design typically retains about 60% of the rope’s strength, making it practical but not as strong as some knots that better distribute load. That’s why the 60% option is the best choice. The other percentages would imply notably higher or lower strength retention than is standard for a clove hitch.
