It seems to me that the fan metric is not correct when we query the amount of fans on post creation date.
I'd like to calculate the organic wall of my post which comes from the following formula:
Organic reach per post/ amount of fans on the date of creation of the post.
I noticed that the amount of fans queried per month was right though, But it doesn't match exactly to the calculation i want and forces me to create a different query.
Is there a way to calculate what i want with one query?
