Better yet why is something this important not handled like standardized tests? Serialize ballot images, upload, resolve disputes in interpretations, continuously test accuracy of reviewers, kick out low agreement/accuracy readers, double review every image. Then make publicly available the ballot image and how they were recorded (not a feature of standardized tests). Paying 15 cents per ballot, every ballot coast to coast could be counted (twice) for under $100,000,000 total cost and virtually anyone with a computer could contribute and there would be 100% audit trail. Given what government spending is, it would be a drop in the bucket.
