Well im no expert in this but it seams like simple math to me,
Every thing under "objekt settings" translate to x 1000lbs
so a setting 1.0 is ecual to 1000lbs required to kill it,
therefor if a setting to 0.0015 requires 10 para to kill it then 1para=0.15lbs
And that gives 0.15x6=0.9, so a setting to 0.0009 should be what u looking at.
Or is that not how it works ??
