I'm going for around 1000-2000 XP per session as in the core rulebook - less to start, getting more at higher level. My first game, one PC died, the other did very well and by the end of the night had 1500XP and had levelled up 1 to 2. The next game will be set 2 years later with her PC 2nd level. Normally though I don't plan to give much more than 1000 XP/PC/session at low level, unless they do exceptionally well, but as I'm taking an episodic approach with months or years between adventures I don't mind them levelling up frequently to start with.
