Daily lucky box points

I was just trying to figure out on your Cashwalk app in the Daily Lucky box. How is the coins calculated? I rarely get anything above a one I can double up to a two. I walk daily with a friend and she always get a six or higher I started before her And she join from my invitation, but she is way ahead of me as far as points because my total is @ 14 daily from the lucky box and hers is much higher.
