You keep hitting this and keep missing the point.
They hid that the payouts were smaller per page (Which people had figured out by comparing notes as to payment) over time. Yes, there are more books in KU, more users as well. That's apparent.
The relevance is to the fact that everyone was using the old page per book numbers, which were quietly changed over time. Sure, it showed up on the landing page for the book... But you know what I don't check every day? The page counts on the books. It wasn't until I noticed the latest book being so "short" when it wasn't elsewhere that I put it together.
What this dis was "trick" me into thinking my sales had fallen off, even in KU. Regular book sales were down (more people in KU, great deal, so why not?) but at first I was getting as many books read in page counts. Then it cut in half or more over time... Making it seem like I wasn't getting the book reads that I used to.
At the same time, they've also expanded the program, so there is more competition for books being read, and the pool was never large enough to start with. It's a fraction of the ten dollars that people pay into the system, for ten book loans per month. If you read them all, and they are long books, then the amount paid to each author goes down. A lot.
That IS the system they spoke of to begin with. It's only the fact that instead of counting the pages as they did originally, they quietly altered that. I nearly quiet, writing, several times because I figured that no one was interested in the books.
When I adjust to the new lengths,(reducing the number of pages per book) all those people are suddenly back, even if I'm only making a fifth of what I used to.
I'm not claiming they've done anything illegal. Just that they used accounting tricks in a way that ticked me off, because they didn't announce the changes made. KU isn't working out as a program and probably couldn't, long term for me. The pool size was always off, compared to the initial payouts. (They use a fraction of what you pay in for that, probably about two dollars of it, for the pool. Hence, with KU being bigger and well used, the payouts shrink. At first, it was richer than that. That's all on the money side. For that portion of things, at least.)
I don't even think that Amazon is doing to to save money or take a bigger cut like you seemed to think I was saying. They simply hid that people were making less, by making everyone (not just me, a million or so people, ) think they simply weren't cutting it any longer.
As far as I can tell, they've dealt with the scammers, eventually. Cutting page counts is NOT in any way a response to that though. Why would it be? That wouldn't help their algorithms at all, in particular. My guess is that they cut the page count to keep people in KU. (The authors.) It was to hide how little people are making in these later days that way.
*I tend to get what are considered large numbers in KU page counts, even with the reduced pages per book being used. They've also been paying less. At a certain point, that means authors are going to leave KU, because it becomes more cost effective to go wide, instead of all in on Amazon. (They force an exclusive contract, if you want to be in KU.)
For instance, the other day I had 40,000 page reads. If my average book is (the old numbers) 450 pages, then that would be about 88.8 books read, plus about fifty regular sales. If the average for what Amazon is counting is 200 pages (for a 100,000 word book) that's 200 books read in KU and fifty in regular sales.
I know that it's a psychological difference, but that, plus the lag of page reads (meaning my books, popular in KU don't trend as well all the time, without a large advertising push, and then I still don't make as much as I used to, since KU is paying less and less...) gave an impression that is very different than reality.
My sales haven't particularly dropped at all. In fact, they've gone up over the years (as far as readership goes) which is wonderful!
On the other hand, at the current rate of dropping, being in KU even with that readership, will mean that my monthly income will probably drop to about a thousand a month or so. I would have some struggles living on that at present.
Hence trying new things! I would have to expect a lot of people leaving KU, as this happens. many already have, I hear.
