I think you may be under a false impression SmartAlyx. The Battle Arena Calculator uses the direct battle code from Dragon Story game data. It is not just based on observation or player obtained statistics. You should check out the page. While the page hasn't been updated in a while (like the dragon rarity list) the code information does get checked occasionally and it has not changed.
