Your average of 200 is kinda the point. How are writers putting out new books and within one month landing as many reviews as you?
That's ratings more than reviews. The average spiked when Amazon put rating in without needing to comment.
There's nothing odd about it either.
It's simply a rating to sales and full reads ratio.
As long as the book evokes the need to rate or review, there's a direct correlation between sales and full reads and ratings/reviews.
Some books simply don't evoke any need to rate them. Readers come to the end without any emotional reaction.
On the other hand, some books generate such positive or negative reactions in people, that rating or reviewing is almost guaranteed.
And some authors are very good at this. Hence their books get a better ratio.
The ratio changes according to rank and time out, which is why I wanted to check rank on an example. PM me a link, and I'll comment generally if I see anything worth commenting on, without identifying the book or author.
But for arguments sake, a month old book which still has a rank in the top 20,000 could be be expected to have 300+ ratings. If it's in the top 10,000 still, then 500+ upwards is very likely. The rank shows tangible sales, and from tangible sales comes ratings. (inc. KU downloads).
By a month, mine are usually 50,000+ in rank, after starting somewhere around 2,000 on day 1. My ratings tank out as the rank drops, although I often get batches of them come in, often after a rank drop, which makes no sense.
