calculate mean once instead of 2n-1
in:
Line 23 in c05f7f7
we calc for each line the avg 2n-1 times. instead taking it out and calc it once.
So what we need to do is to extract the avg calc out of the func (and rename to something much more specific). and then pass the arr of results into the func.
