Answer - when it's posted on amazon!

I recently noticed that one of my novels had taken a sudden dip in overall score - dropping from a 4-star average to 3-star average (12 reviews at that point). I hadn't received any additional negative reviews or similar, yet was suddenly, unexpectedly lowered..?

It's subsequently come to light that amazon has recently changed its scoring policy to the following ...

"Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases."

I received an additional 5-star review last week - taking me back to a 3.5 average. Then, another 5-star review followed this week - yet it only increased my average by ... 0.1!!! (which is massively disproportional considering I currently only have 14 reviews..?)

I find it a bit unfair that amazon does not recognise the worth of either older reviews, ones that cannot be verified as purchased, or, reviews THEY tag from old paperback editions etc . . . Rant over.

Has anyone had similar issues..?
