It was a small little bug in the game, where you could earn the "Score X stars" XPs by attaining only 5% and 10% of the total stars respectively. In the case of a 10v10 war, that's 1 star and 3 stars (personal experience right there).

So a 3-star in such a war yields up to 5XP + 10XP + 25XP = 40XP. However it has since been rectified and now it's back to the normal 40% and 60% of war stars.
