The analysis here is using publicly available data and they are pointing out statistical properties of that data that they say are highly indicative of manipulation. They are giving enough information for outside statisticians and others to reproduce their work.
This is not at all comparable to most of the claims after the 2020 election. The closest comparable claims in 2020 were some of the claims based on some vote distributions in some districts not obeying Benford's law. Those didn't hold up because given the demographics of those districts Benford's law would not be expected to hold.
(I wrote a web-based simple simulation using data from one of the states that the people basing claims on Benford's law were using in order to illustrate how much the distribution could differ from a Benford distribution. Anyone curious can find it here [1]. There's a link on that page to run it).
But this time around it's not going to face honest scrutiny in the courts so they won't have to admit they have nothing.
