@Switch BlaydeWell, if you're already making the adjustment, then it's not an issue. I was just pointing out why those posting should consider it, which again was the original question.
As for not believing in economic theory (i.e. Supply and Demand), most economist's don't believe in it either, arguing that it's like driving only using the rear view mirror. So, it works for me, which is why I first started making the adjustment. In short, it worked for me, and improved my sales, as expected. If you got there without even considering economic theory, it really makes no difference. What works, works, yet it's not always obvious which strategy does for most 'self-published' authors. Again, the reason why self-published books now have such a terrible image, is because so many who do publish via KDP simply don't know much about a whole score of things (i.e. their just not that good of storytellers, not that they don't know the proper way of doing things).
As noted, in a compelling story, you can forgive a lot, yet if it's not a good story, why would anyone even consider reading those authors. Again, until a couple of years ago, KDP was a well-regarded publishing source. Now, there such a prevalence to terrible books, the whole industry is no longer much respected.
By the way, I quit using ANY for of Kindle a long time ago, mainly using Bookapy. But, once I've completed posting and I'm no longer updating the story, then I post to KDP so readers who didn't purchase it WHILE I was posting, can access it Amazon. But again, the profit discrepancy, at least for me, is abysmal on KDP compared what I earn on Bookapy.
But then, being 'on the spectrum', I'm in a niche market, simply because my books are NOT easy to read. However you read it, few will EVER read my writing, just because of that alone. People avoid me as much as they can anyway, so why should the marketplace? I'm used to it, as it's merely a fact of life.
Which again, is WHY I get so much flak on the forums, it's not my points, it's simply the way I talk, think and deal with life. Yet again, thanks for reminding me, once again, I'll simply quit the Forum entirely, as I've long done.
As I've noted before, I learn more, writing for myself and not publishing anywhere, so in that case, why even bother publishing anywhere. Again, I've got a niche following, but the vast majority of readers, authors, can't STAND anything I say, do, say, or my mere existence—which include here as well.
Posting on SOL boosts my Bookapy sales, but … I'm much happier NOT conversing with anyone. Friends are beneficial, yet for me and 'my kind', friends have always been an extremely rare event anyway.
