I guess all I can say is if the GetBonePosition function is returning the local origin instead of the offset from the global origin.
And I was thinking something like, vector v_direction = NewBoneOrigin - PreviousBoneOrigin; float length_moved = v_direction.Length2D(); // I dont remember the magnitude function, its something like Length2D. Then you have a distance traveled plus a direction of movement which you could clamp how you see fit. length_moved could be used to determine a velocity for that frame.
