I thought we didn't know that there will be a goon in the game so I did this math in advance (in this post reply window, meaning that it wasn't copypasted) to conclude that there is no way to improve our chances to better than 50%:
D1 shared victory = 50% of winning
D1 lynch = if in fullVT setup:
--> 25% chance of losing outright, 75% chance of going into
-- --> D2 with choice between 4/7 chance of winning with shared victory (real probability is 100% but we won't know that) and:
-- --> 33% chance of losing outright, 66% chance of going into
-- -- --> D3 with forced shared victory because nobody can get lynched, win
chance of any individual to survive until D3 = 50%
chance of any individual to win as town if a townie is lynched and town goes for shared victory D2 = 3/4*4/7 = less than 50%
Unfortunately that's useless now.
