I got my order with 5 star than 2 other with 3.3 and 2 star
After that I got 5 star rating ,my star rating became( 3,9 ,I was not sure may be its 4.2)
after a moth I saw my rating automatically became 3.9)
Now after whole month I got another order with 5-sTAR rating but this time my rating improves only 2 point ,and 4.1 is showing .
Now will you please tell me your experience that ,now how many 5 star reviews I needed to get back .
I am really worried about that ,If some could help me .I will be very thankful to him or her.
Hope to hear from you soon

Do it yourself. Use simple math to add up your current and potential future reviews and then calculate the average.
