I have a 96%. I have only had a couple truly negative reviews and a few 4 stars. Which, in my opinion, aren’t negative… I get more 5 stars then anything but I still sit at 96%. I know I will never have 100% again but will it ever go back up?
Your percentage is given by (num. of stars you have) / (num. stars you’d have if all were 5*).
If that number gets bigger than 0,995, you’ll be back at 100%.
