Let's look at some numbers.
If there is only one mafia team opposing the civilian faction, I believe there are only two ratios that are remotely likely: 15:4 or 14:5.
One mafioso is gone. 15:3 or 14:4. To be safe, let's project a dead civilian this night phase and one in each future night phase.
14:3 ---> 5 mislynches available until a 4 vs. 3 LyLo
or
13:4 ---> 4 mislynches available until a 5 vs. 4 LyLo
If we take a
better safe than sorry approach, we should assume the worse scenario with the larger mafia team. Either way though, we arrive at the same necessary POE pool:
5 mislynches + 3 living mafia members = POE pool of 8
4 mislynches + 4 living mafia members = POE pool of 8
So 8 is the present target.
If there are multiple mafia teams or any independents, this dynamic will need to be adapted. Given that Mac flipped merely as "mafia" instead of some specific team name, I doubt there are multiple teams.
