Did minimum royalties earning change without us being told ?

[Tuyres]

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$ :

For stock customers who are on standard subscriptions, the minimum royalty applies. However, some customers have custom subscriptions, perhaps for much higher licensing levels, and those royalties can be lower.

Custom is very special. Minimal royalties may be below the 33 cents. It is indeed not documented, but it looks like the royalty is a complex calculation of what the customer pays and how much they download.

Ok I see. I checked and indeed all those lower amount of royalties seems to come from custom licenses. Still they could probably add something about it in the documentation because it's a little bit misleading but I'm glad it's not a bug.

It looks to me that the documentation is sometimes not updated when the situation changes. When the documentation was written, there was no Adobe express, and the "unlimited" plans did not exist.

Can it be because of the currency conversion. Like when buyer use debit card of his currency to pay on Adobe and while converting it may result in a bit difference?

It's my thought only.

There is no currency conversion here. Adobe is working internally with a credit system. And a 10 assets per month subscription is costing everywhere the same (in credits). And that make $0.99/asset.

They should, however, update this to reflect the reality.
