I wanted to pick option 5 since misery loves company and I'm a bit demented myself (ohsnaptosis, my bad you said tormented, nevermind me) butI went with option 4 honestly because I liked the presentation. I wouldn't call it a revelation but the logical deduction is noteworthy.

I don't think there's onlyone 5.5 in every square 110 tho. Thasalota land and there's probably a few more that are just that elusive to never be counted.
