Care to explain why, if this is the case, static ropes don't explode from being abseiled on in non-ideal situations (canyons/caves and the like where slumps or even GASP short falls are common)? Or jumared up (which involves bouncing up and down, which is surely comparable to "slumping" in a loading sense)? Or used as a backup for Industrial Rope Access work, where they're expected to hold a fall, should the main line fail?

ps. Some other questions for extra credit:

What is the loading increase between a 50cm fall and a 1m slump?
Does the above have anything to do with micro-fractures?
How many kilo-newtons does a 10kN shock load produce?
