You're probably right, but the question was (in David's and my interpretation)
strictly referring to dynamic stability. You've interpreted it as asking "what
software do I need to satisfy the regulators to let me fly a class 3 rocket"
and I suppose that's a fair interpretation or assumption, but it would've
probably been helpful to make that point clearer eg. Carl might (granted
unlikely) have already sorted out the dispersion analysis with other tools.
