Doing the EX roulette gives at least 70, doing 8 Alex runs (2 for each floor in a pf group) gives 80, a single game of seize rock gives 20 (and you can do a lot of PVP with yer mates)

Often times I do my expert, help a friend of 2 with theirs, help others with Alex runs and then just PVP a bit, not hard to cap day 1 if you play PVP.
