I'm so confused how you are getting 7 total players on Day 4. I posted the details here.
To take it out of that quote block:
D4 (Actual) Final Tally:
genny (6) - AM, Coop, Miz, cubs, Wondering, Stroganoff
Coop (2) - dolphin, genny
Coopah's Hypothetical Example if dolphin were villager:
genny (4)
Coop (4) - dolphin, Wolf1, Wolf2, Wolf3
In case it's not clear -- and to pre-empt anyone who might misunderstand my posting after the game is over -- I'm so happy you were right about dolphin! I'm just trying to wrap my head around this wolfhunting exercise so I can actually learn something from playing this game for next time, because you sniffed dolphin out using this method, and she was still on my village/neutral reads at that time.
The actual D4 tally was 6 votes on genny and 2 on you = 8 total people, 8 total votes. You were saying that dolphin has to be a wolf because if she were village, the 3 wolves + 1 villager (dolphin) would give you 4 votes. But then there's still 4 players left, so those votes could still be on genny, resulting in a tie.
If the votes between Coopah (4 votes) and Genny (4 votes) resulted in a tie and both of them died, it'd go from 5 villagers + 3 wolves (8 total) to 4 villagers + 2 wolves (6 total). Then after night kill it's 3 villagers + 2 wolves to start Day 5 in a lylo state. The bottom line is that even if dolphin were a villager and even if all 3 wolves rushed the vote onto Coopah (4) to tie with genny (4), it's not a guaranteed win for the wolves as Day 5 would start with 3 villagers + 2 wolves (lylo).
So in case that's not clear, there's still the possibility that dolphin was villager in that scenario.
