Unless you have a different meaning of weighted average to me, I don't
think you do. AFAIK this would produce exactly the same result as what
your code does:
state_function(state,weight,value) state[0] = state[0]+weight state[1] = state[1]+weight*value
final_function(state) return state[1]/state[0]
The state[0] is the same as your _sumedWeight. Because it's a constant in
the second loop you can do the division after. state[1] is your
_sumedWxV times _sumedWeight.
Have a nice day,
