Charile, So, this served a great purpose, hopefully convincing some people that this particular election event had integrity. I think it will be healthy if there will be multiple probes that will make people more confident. Probably not all, but at least some.
As to methodology, I don’t know details, but it makes sense from your description. you apply approximate automated matching process that identifies cases of potential errors. Then, they presumably report it to lawmakers who have an ability to go verify those errors. As you are saying here, this establishes an upper bound on the error.
Still, if you think that this will reduce enthusiasm of Trump supporters, I think you are wrong. Overall feeling of “injustice” is based on the history of multiple unfounded attacks on Trump over his whole term, and on “legitimate” changes to the voting process that made it easier for “low affinity” voters to drop their ballot in the mail. Some people are channeling their frustration into out-there theories but these theories re not the root cause of the voter frustration.
