Hard to tell, it really depends on how difficult the next event will be. Also, your luck(because of RNG) always plays a big part in the end. The other problem is that, the difficulty of each maps can vary greatly. Usually E-1 and E-2 is easy even at higher difficulties, while maps like E-5 isn't all that easy and still heavily relies on luck even at the easiest difficulty.

Oh well, I guess the usual standard of "At least 4 ships at level 50 for each ship type" should still suffice for lower difficulties.
