Also curious about that, because I also assumed we'd use Perception as that's how it was the one other time I played Pf2E, but then the sheet has a separate field for "Initiative", which has a different value (that's not based on Dex either, apparently...?) 

If we do use Perception, it's a 6 instead of 1, so I doubt it matters either way in this case.

I saw that on my CS too, but according to Initiative rules I read over, the DM can call for an initiative roll using one of many different skills (like I think one of the examples was if you're starting an encounter while sneaking, you could initiate with Stealth). So I am under the impression that that's an ongoing modifier to ALL initiative rolls you make. Like if you had a feat that gave you a +1 ongoing to Initiative or something, it would show a +1 there and you roll a Perception-based initiative, then it would be "1d20 + Perception + 1"

But ofc, I'm completely new to Pathfinder in general, let alone PF2e, so people more experienced than me, feel free to correct me if I am wrong!
