Research is the anchor problem
This branch is single-sourced, like the whole research tree, and marked that way rather than hidden. It also matters more than it looks: research multiplies Alliance Duel points, by different amounts on different rows — we have watched one screen show ×1.00, ×1.70 and ×2.05 at once. That is why every duel point value on this site is labelled a base value, and why a guide that prints one without saying so is telling you less than it appears to.
