It depends on how skilled you are as a player. The alliance rating is the sum of the pi for everyone in the alliance. Even your highest, 600k+ is only 20k per player in a full alliance. I would suggest 3 million as a good but not great alliance (average of 100k pi per player), though that's overall, not for me personally.
