The following calculation is not always accurate because it relies on the discrimination of sheets and BMD ballots by using the file size alone. If there is only a single sheet or if Sheet 1 has content on both sides, while Sheet 2 only has content on one side, then this may work well for ES&S ballots, which have a very small BMD file size. If this is not true, then some styles of Sheet 2 will be misclassified as Sheet 1, and the number of ballot images will exceed the official report.

Also, this calculation does not take into account repeated images in the archives.
