The first half of what you listed as being statistically relevant (up until the ellipsis)... Are just random data points. With a sampling of 60 albeit complex events - meaning elections - there are statistical outliers that can be identified in every election. There's a county in WA that has voted for the presidential winner in every election for 80 years and they voted for Biden this year. We haven't had 2/3 voter turnout in decades, but it is not unprecedented. This is a highly charged political environment and a very polarizing President. I can tell you that every rally that Trump put on and was live streamed did as much for Biden as it did for Trump. None of the items that you listed are individually or collectively statistically relevant.
Regarding Biden only ballots - I have not seen anyone credibly assert that there are 200K of these ballots (only anecdotal accounts from various affiants and speculation by people who have attempted to quantify things). The theory that Powell put out is that those Biden only ballots were fraudulently introduced to replace Trump ballots in order for the recounts to match the flipped data. That's great... all we have to do is recount one down ballot race to see if they are off anywhere close to 200K votes. I'd like to see that happen. So far, there have been several down ballot recounts in local jurisdictions that have not been off.
