Through a dumb screw-up I took a 40 foot fall on to a 13 Bluewater II once. I guess it isn't completely static, but only 'low elongation' because I was totally fine. Some energy could also have been absorbed by it whipping through shrubs. I probably had a little over 100 feet out total, running down from a tree at the top of the cliff with a big loose loop. I was clipped in with my GriGri and fell from a route anchor to just above the ground.
I wonder what ropes people are using for haul lines and what the actual elongation #s are. For the 13mm BWII it is 3.8% at 300 lbf and 8.4% at 1000 lbf. Are haul lines even more static?
Soon, wouldn't you be going around 80 mph after freefalling 230 feet? KE almost 43,000 foot pounds?
