How does GA calculate the correct number for metrics (Ex. New Sessions %)?

I am new to Google Analytics and would like to know how it calculates the correct number for metrics such as New Sessions %.

 

The final number it comes up with for New Sessions % is not the same number I get when the data is separated by week and I try to average them all.  I have not been able to find a concrete answer for this, but I have read that Google does behind-the-scenes calculations when zooming out from day to week or month to year.

Hi @Branden R - GA uses

ga:newUsers / ga:sessions

Where newUsers counts the number of sessions made by users who have never before been on site.

 

Kind regards,
