IMO 'day x is too soon' is totally dependent on a number of factors...number of players and whether more valuable roles like cop are already out there being top of list. The game feels mature enough to ask that of you now.
I don't see why what you claim to be able to do on odd nights can't be in some way validated. You either gained some information, that you can tell us, or at the very least, if what you reveal is already known, we know what you can do and you can prove it next time you use it. Unless it is an ability that literally neither reveals nor does nothing, how can it not in some way be validated? What role could that even be? Genuinely curious.
Second post: I see you are fixating on N1. It's not just about N1, it's about revealing what you actually do so you can be held to it later.
