Did minimum royalties earning change without us being told ?
Hello, I'm not sure I understand how the minimum amount of money we earn per download works. It might just be me misunderstanding something, or me experiencing a bug, or that a change has been made and not communicated to us.
So, what do I have to understand from this :

Does it means that once I got 1000 downloads my minimum earning per download will now be 0.36$ ? Because when I reached 1000 dl I noticed this change, my minimum earning went from 0.33$ to 0.36$. But since a few months, I'm starting to earn 0.35$, 0.34$, 0.33$ despite having over 2000 dl. I didn't really bother, but today I earn a 0.32$, which seems a little bit odd to me since the minimum garanteed have always been 0.33$ to my knowledge.

I've noticed the change around the beginning of the year, but cannot find anything about it, do you guys have any clues ?
Here are my last sold images with a 0.32$ :
