This is a simple statement of statistical pattern weirdness in the bulk voting record of a county.
I'm in Australia, I have a geostatistical and epidemiology background using such things to find valuable mineral deposits and early signs of unusual diseases.
The statements made here are far more convincing of actual fraud than the 2020 claims .. if this repeats across many county's then it becomes more and more certain.
If it's no more than a blip in a single county then it's just one of those things, for it to be fraud there would have to be similar patterns in multiple counties in swing states.
The future then is a right old bucket of worms.
Assuming it was actually audited. The one I'm most aware of (one of the Arizona counties) was called an audit, but it wasn't an audit - it was a recount.
It is a bit like the weird jump in scandals out of politics between the pre-internet era and now. It turns out that the press just didn't report on a lot of things. Voter fraud will be similar, as the data becomes more public and people start coordinating more effectively a lot of dross is probably going to get turned up.
We've got some issues to deal with
