These matchups are this site's own model, not values from the game files. Damage per hit is resolved class by class against the defender's armour, turned into DPS with reload time and projectile accuracy, then weighted by resource cost (gold and stone counted at 1.5× food and wood). A trade has to be 1.5× lopsided before it is listed.
