Astuce : demande une double estimation bottom-up (nb de clients potentiels × prix) et top-down (part d’un marché global), puis exige que l’IA croise les deux pour valider l’ordre de grandeur. Ajoute aussi un intervalle de confiance et des sources publiques (Insee, Xerfi, rapports sectoriels) derrière chaque hypothèse, sinon les chiffres restent spéculatifs.
