A couple of months ago, I went on vacation and forgot to activate the vacation mode. While I was away, I got an order which expired and was subsequently canceled resulting in a 1-star review. Up until then, I had consistently received 5-star reviews except for one client who had given me a 4.9 (and then proceeded to give me an awesome review and promised to come back for more orders ). That 1-star review made my overall rating drop from 5.0 to 4.9.
Since then, I have completed tens of orders with a 5-star rating but my overall rating is still stuck at 4.9. So my question is, how many more 5-star reviews will I need to get to do away with the 4.9? Is there a formula for calculating this?
Thanks in advance
