One of my buyer gave me 4 star rating my overall rating fell to 4.7 / 5. Can I ever reach again to 5 star rating?
Yes. You’ll just have to earn more 5-star ratings. The ratings are a mathematical equation – an average, if you will. If you want a higher average, you’ll need to earn a number of new high star ratings.
If you asked me, I would say NO. I think the best you can do is 4.9. I don’t think the logic would round up and the best the math could do it 4.9999999999999999 which would just be shown as 4.9
