You're welcome on all accounts. :)
Excellent screen shots.
Looks like it is time to email them. There may be some sort of regional royalty pricing going on, but I believe it should always be the same based on what you put in the second screenshot where you chose 70%.
Might need to email amazon. It'll take a day for them to get back to you, but it will help determine what is going on.
Do you have a different book in your account that is priced at 35%? That might be showing up.
Thanks. I'll e-mail and let you know what I found. There's only 1 book so far.
