Interesting. I noticed right away the Dominion software version was 5.5. Is this another meaning for Q's use of 5:5? It makes me wonder.
This is from Ron,there is more at link.
Look in the “C:\path\to\project\NotCastImages” folder on all the ICC hardware for ambiguous ballots. Arizona had a lot of issues with sharpie markers. The ICC hardware might have marked such ballots as ambiguous.
Ambiguous ballots are not counted, but are saved to a folder.
