Did you see the announcement for KENPC v2.0 effective February 1, 2016? If not, back up to the Amazon KDP Support page (or click that link above), and look for the articles on the right-hand side.
You can also read about it on the KDP help pages: https://kdp.amazon.com/help?topicId=AI3QMVN4FMTXJ.
It says that on average, titles aren't affected by more than 5%, though some titles may have a much larger change in the KENPC.
They are putting a cap of 3000 pages on the KENPC. Wow! That's a long book. I have a couple of boxed sets with 2000 pages, and I thought those were extremely long...
I checked on one of my books with about 2000 pages, and it's almost identical to what it had been (2039 pages).
In fact, I didn't notice any significant changes with any of my books.
Have any of your books changed KENPC significantly?
If you contact KDP support, telling them that your KENPC v2.0 went down substantially compared to KENPC v1.0, and that you would like to opt out instantly due to this unexpected change, perhaps they will accommodate you. It can't hurt to ask. In the past, when they've introduced substantial changes, they've provided an opt-out clause. While it may not be substantial for most authors, it does appear to be substantial for you. From 42 to 29, for example, that would have a drastic impact.
I don't believe any of my KENPC's went down (the ones I checked were almost identical to the previous values), so it's possible that they haven't diminished across the board.
Mine didn't change as far as I can see. But mine are pretty straightforward, standard formatting and all that. No extra spaces thrown in or spurious pages as some insert. No overly large fonts. I imagine this newest change is driven by factors similar to those that motivated the switch to KENP was in the first place. KENP was created to counter scammers; I suspect v2.0 was developed to counter those who found ways to game the system. It's possible I'm wrong. Perhaps Amazon is just greedy...we have so much to steal.
My novel dropped more than 10% - from 728 to 633. Pretty straightforward formatting throughout, except for maybe 4 or 5 places where something quoted was set apart by a space above and below... really not in numbers in excess of what you'd see for scene breaks in most books. So I don't get it. But it still comes out (assuming the 'just under half a penny payout' that it has been) to slightly more on a borrow than I'd get on a sale - so I guess I won't whine, either.
I had one of my 15 books drop 12.5% in KENP. Just emailed customer service demanding an explanation as to why this one title was singled out to be dropped disproportionately compared to all of my other books. I've been noticing them dropping the KENP pages for a while on new books with the same word count as older books with an existing KENP. I started a thread about it a while ago but no one seemed to be interested then. Now, they're lowering the count across the board to reassess the older titles. Just another way for them to save a buck. I suspect they are doing this to stabilize the per page payout because it has been dropping rapidly. I guess we'll find out on the 15th. I'm going to predict the rate spikes to .0051 now. It will drop again but people won't whine about it as much as if it stayed where it is with KENP v.1 and then dropped anyway.
The average KENPC will change less than 5%, although individual books’ changes may be larger or smaller.
I particularly grinned when I saw that statement by Amazon. Mine dropped by exactly 13% which would amount to about 26 cents per book based on a half cent per page payout. The format and fonts are pretty normal and everything is straight text with no gaps. I though was expecting this when Bezos lost some of his net worth last week. The 2.0 was the backup plan in case they incurred losses and books were going to be the number one quick target. What other area could they start with so quickly and not have sellers howling.
All seven of my books dropped, from as little as 12.54% to as high as 14.91%. The total of all pages in KNEPC 1.0 was 7920, and under 2.0 is 6901, a reduction of 1019 KNEPC pages, for an average of 12.87% drop. If I now have complete reads of each one of my books, I'll earn roughly $5 less income because of the page reductions. ($4.70 at the last payout of 0.46 cents per page, I think).
I'm one of those series writers that places the first chapter of the next book at the end of most of my books as a teaser, which is then repeated in the new book. I also have a repetitive Persona Dramatis, and an About the Author at the back of each book. They may have considered these not worthy of a "read" when they will be seen again in the next book. But one long book lost 220 pages. I didn't have nearly that many extra pages in the back of my book to possibly be chopped off.
I had two short stories with an increased page count of 1 page and 5 pages. I had thought that my prior page count had been slightly low given my word count, but at my level of borrows it hadn't seemed signifIcant enough to make a fuss over. Approx. a month ago my page count had briefly dipped by several pages before returning to normal, so I wonder if there had been some beta testing going on at that time.
I single space using Palatino 12 point font, and then I convert the file from Open Office into a kindle friendly file (can't remember if mobi or ePub) using jutoh. I have the lines set at .10 as per the kindle guidelines.
