Try checking the weights for both your shock cord and parachute. Both seem to be much too heavy for their size. I don't think that your shock cord weighs 25.0 oz., and I don't think that the parachute weighs 21.9062 oz. either. Remember, garbage in...garbage out.
I made a couple of small changes in your RockSim file. I corrected the shock cord and the parachute. This should give you better results.
