From the AV/Aventine QT in Beware of Bites:

I could look across past games to see whether wolves are more likely to try and infiltrate by claiming, or clam up, but even with how often I do it, there's hardly enough games for such research to be anything but a crapshoot.
Kinda curious what others think of this, on a meta level. In both HP and Villains the wolves claimed fairly late and only once the towniness of the person they were claiming to was proven beyond a doubt (despite the fact that I provided fake-claims in HP), but two games is hardly a significant amount of data. Plus it obviously depends on who the wolves are.
