I've said this before, these calculations while come from a place of perhaps healthy curiosity, they're misleading. First of all the sample-size is incredibly small. Perhaps reach out to Tony, the new CEO and try and get some anonymised numbers across the board.

Another aspect you wanna look at is also the niche. Looking at this list I recognise half the names and they have one thing in common - writing about writing and money-making and just basically copy-pasting each other's recipes of articles about drinking water, coffee and stuff like that. Why is this important? Because the vast majority of successful writers actually don't share their earnings reports and are not part of this niche. I am one of them. I won't give you numbers, but I can tell you that the 2K followers you have, with a different niche could earn you over $1200. The trouble is, what most people don't get, is that having a poor quality large following is worse than having a high quality small following. Looking at Sinem with 65K followers only making 3-4K, it's an absolute disaster.

Finally, you have to account for authors "inflating"numbers, as in just like in the Sinem's case, she made 11K once. If that's not repeatable, then it's not really a valid number. Same for all the others. A much more representative number would be their 6 month or yearly average, though that's not perfect either.
