Ok so the support score is influenced non-linearly by donor score. Is there a particular donor that has donated to the highest ranked 22 projects, that did not donate to the 23 or lower ranked projects?
I have graphed donor score vs rank for the top GiveWiki donors. Does this include all donors in the calculation or are there hidden donors?

Donors have a switch in their profiles where they can determine whether they want to be listed or not. The top three in the private, complete listing are Jaan Tallinn, Open Phil, and the late Future Fund, whose public grants I’ve imported. The total ranking lists 92 users.
But I don’t think that’s core to understanding the step down. I’ve gone through the projects around the threshold before I posted my last comment, and I think it’s really the 90% cutoff that causes it. Not a big donor who has donated to the first 22 but not to the rest.
There are plenty of projects in the tail that have also received donations from a single donor with a high score – but more or less only that so that said donor has > 90% influence over the project and will be ignored until more donors register donations to it.

By the inverse rank in the ranking that is sorted by the score. So the difference between the top top donor and the 2nd top donor is 1 in terms of the influence they have.

Meta question: is the above picture too big?
It displays well for me!
