Methodology
How every number is made.
Every figure in the product and on this site is produced by the six rules below. They are published in full because an analytic you cannot interrogate is an analytic you cannot act on — and because a number that arrives without its rules is a number somebody can argue you out of.
This page is the specification the product is held to. If the product and this page ever disagree, the product is wrong.
Six rules, each one citable.
Every rule has a permanent address. Send a creator, an accountant or a sceptical operations lead the clause rather than the page, and they will land on the paragraph that answers them.
The three grades, and the rule for issuing each one.
A grade is not a confidence score. It is a statement about where a number physically came from, and which of the three it gets is decided by the source, never by how sure we feel.
Attribution, and the three things it refuses to do.
Deciding who earned a sale is where most of the arithmetic in this product could quietly be made flattering. These are the rules that stop it.
Pick any date range and check us against the platform.
Put FanOptik next to the creator’s own Statements page. Net per bucket, cents precise, line for line. If it does not match, that is a bug we want reported, because the entire system is built on this tying out.
That offer is the whole pitch, and it is the reason every rule above is published in full rather than described in general terms. A methodology page that could not survive being tested against the source would not be worth writing.
What we will not claim.
We have not found another tool in this category that publishes how it handles the platform fee, refunds or partial days. That is a statement about what we have been able to find, not a claim about what exists — we cannot see inside anybody else’s product, and we will not pretend to. If you know of one, send it to us and we will link it from the references page alongside everything else.
The same restraint applies to every competitor statement on this site: their own published material, linked and dated, and “not published” is never converted into “does not exist”. Where we have broken that rule, it comes off the page and the changelog says why.
