When the final Mafia is lynched on Day 4, there wouldn't be a NK that Night, so only three townies would die and 9 would be left. I know it's not really important to the guide, but I'm picky like that. :p Good stuff, though, it's obvious you've put some work into this.The best case scenario is to lynch correctly each time, being 4 lynches and 4 nightkills over 96 hours, leaving 8 townies left.
/in for IH's Fire Emblem, btw.
