agentcarr16: I'm not sure how I feel about the wonky probabilities that result from the setup.
What are some other thoughts on the setup?
I think the setup is fine on the whole, but might need a larger scale (e.g. 6 pairs with 3 scum), since if town doesn't hit scum D1 in this 4 pair setup, they're probably hosed no matter what. And even D1 isn't quite 50/50 since scum can coordinate at least enough to tip the scales.
As Krypsyn pointed out, by D2 (the first point there's really any data at all) they either need someone from town to suicide, or scum to bus, neither of which is really all that viable.
