How do you know that the factor is 1 for all? Where it is said?
If you check the rules on the 1st page of the ANN it clearly states that *1 for first 10k onions and anything after that is *1.2 . If you core factor supporter it will be capped at *5 for the first 10k pending which core factor.
Can you please post scr or link?
Or can you read here

Factor is variable not 1.
