First of all, excuse my rapid questioning guys!
That's what happens when you haven't played a PnP-RPG before, you have too many questions!
To the point, are the wilderness chases counted in rounds and by having the fleeing/pursuing groups moving at running speed on a grid? Or they're counted daily (as it says on LL Core Rules, page 52) and you move the group randomly in other hexes of the world map? An example would be amazing to have.
I looked on Rules Cyclopedia, the whole evasion thing is kinda similar to LL but at the same time confused me even more on how to handle wilderness evasion. The "if the pursuers are faster, there's 50% chance they catch up to the escapees" is totally dropped, and the wilderness chase is very similar to a dungeon chase.
