I fully believe you because I've beaten all of them you said you did. 23 can actually be done if you just loop a single pattern, 13 and 17 I haven't even found a "2 Path Clear" (you use one Aratron stone to activate the other two, it's technically 2 demon but also not?) for those two, like NuSan has 10 and 12.
I uploaded a video of all my 2 demon setups if you're interested in seeing what I did, but I'd love to see your own screenshots too. You could've found fewer stone/fewer step setups. Hit me up on Discord or smth so it's easier if you wanna! (@holoknight)
