Impressive!
Mine always eats right away (live) but I've only seen him fully coil once and double coil twice. Usually he uses single coil. Mind you, if the mouse starts kicking too much he starts ratcheting that one coil down tight. One time I thought for sure the mouse was going to just explode - his eyes were almost all the way out of his head. Imagine what kind of squeeze he could put on with 2 or three coils! Amazing strength!
