but would it be stronger if we used it on a later day with more info?
If you think of it as just "we get an extra lynch", it isn't any strong or weaker depending on when we use it. And right away increases the chances that we'll get to use it at all.
right but usually day 1 scum can manipulate town much easier then other days i feel. So i think if we use it day 1 there is a higher chance our extra lynch hits town.
If we knew how many scum there were, it would help in figuring this out. But still, I don't think you are right.
In a 3 v 10 game, which is the f.ds norm, mafia is at its weakest on Day 1 in terms of wagon manipulation. They're 3 of the 7 it takes to lynch. On Day 2, if we mislynch and have a death, it's 6 to lynch and mafia is up to 50 percent.
I think the "extra" lynch coming on D1 is better, in a vacuum.
And again, it's a group decision, so it's not really a vig. I think, given the claim, this is how we should use it. Whether we use it on D1 or not, we'll see. ADK can always make that call anyway.
The other way to use the dayvig is as a counterclaim cleaner -- that is, had he not claimed, and then later we had two people who were in opposition over a claim, ADK can just kill one to confirm the other. That's off the table, as the power is out there.
