For people talking about a minimum or set number of encounters a day - that is really hard to do in a story-focused RPG. I mean if the story has you as a caravan guards traveling from Baldur's Gate to Waterdeep; that is about 40 days or so. If we are going to have a minimum of 4 encounters a day, that is 160 encounters on that trip. If you make these encounters medium difficulty, that is going to be enough XP to get from 1st level to around 12th level or so .... while traveling as a caravan guard.
It is a lot easier to do this in a wargame or something like that with no story to influence the number of encounters.
