The Pope called for a crusade for Jerusalem. I sent troops when I could, but I was busy keeping the balance of power on Iberia as Aragon. Anyway, I finally finish my set of wars over there and fully commit to the crusade. Just before the final battle of the crusade, I was third in terms of contribution, with about 18% to England's 19% and France's 26%. Then, I captured the Caliph in battle. I figured that capturing the leader of the crusade target would give me a huge boost in contribution, but when I checked, I still had less than 19%. Jerusalem ended up going to France. Should capturing the Caliph not give a major increase in crusade contribution, considering it results in an auto-win?
