BulletFalloffCurve wth?

[Nolanoth]

I found a file called BulletFalloffCurve, but I have no idea if it's responsible for bullet drop or not. Can someone explain to me how it works?

<?xml version="1.0" encoding="utf-8"?>

          <field name="Type" type="Int32">0</field>
        </object>
        <object name="Knot">
          <field name="Value" type="Vector4">1,0,-0.999999,0</field>
          <field name="Info" type="Vector4">6.2832,1,0,0</field>
          <field name="Type" type="Int32">0</field>
        </object>
      </object>
    </object>
  </object>
</object>

All I want to do is see if I can add some bullet drop.
