Wait do groups not offer XP for getting past encounters peacefully?
When our group tried XP that's how we did it. (We still ended up going back to milestone as less book keeping.)
It doesn't really matter. The point is "advancement based on encounters" (or really any other form of criteria) is incentivizing doing that specific kind of thing, even if a variety of approaches are acceptable. If you don't feel a need to incentivize things, just basing it on time passed will do the same job with less bookkeeping. Its not like levelling as an advancement method isn't kind of arbitrary in the first place.
