This article has a lot of good info about the process that will be used in the Windham, NH audit. Even though they don't have a lot of ballots (as evidenced by the 2 tables of boxes seen yesterday), the auditors expect the process to take ~4 weeks!
What was very interesting to me was the mention of the IBM 5150 chip knockoff. These machines are old! Plus, I could swear I had read where Donald Trump was looking for an IBM 5150 machine years ago. Of course I can't find where I saw that now.

Just to be clear, too, 85% of the state, means 85% of townships, not 85% of distributed voters. The 15% that don't use them are mostly very small-population towns, which means a much higher percentage of the the state's votes do use these machines.
That said, I'm still unsure much will come from the machine audits, since anyone in this state knows the real issue is the same-day voter registration and voter ID loopholes, that don't get audited. Even the conservatives I've talked to in the NH government don't believe the AccuVote machines are a problem (which I'm inclined to believe based on their regular bipartisan tests, and that they were purchased years before the company was acquired by Dominion). I certainly hope something comes out of these audits, but until we audit the same-day registered and affidavit voters, we won't be able to solve the whole problem of fraudulent votes in NH.
Additionally, as you'd expect most of the blue votes come out of the "cities" like Nashua, Manchester and Portsmouth.
