Sans ancre externe, le classement flotte librement : on sait que le moteur A est sup\u00e9rieur de 200 points au moteur B, mais on ne sait pas o\u00f9 ils se situent sur l'\u00e9chelle absolue SSDF ou CCRL. Le grand tournoi seul ne suffit pas \u2014 il donne de l'ordre, pas de l'altitude.<\/p>\n\n<p>Une ancre est un moteur dont la cote absolue est \u00e9tablie par gauntlet d\u00e9di\u00e9 \u2014 des parties jou\u00e9es contre des adversaires eux-m\u00eames d\u00e9j\u00e0 calibr\u00e9s, sur le hardware de r\u00e9f\u00e9rence Ryzen 9 7950X3D. En fixant plusieurs ancres \u00e0 des niveaux diff\u00e9rents, Ordo peut aligner tout le classement sur l'\u00e9chelle absolue, comme poser une r\u00e8gle gradu\u00e9e sur une carte sans rep\u00e8res. On ne peut calibrer un moteur qu'en le faisant jouer contre des adversaires proches en force, eux-m\u00eames d\u00e9j\u00e0 ancr\u00e9s. La strat\u00e9gie est donc une mont\u00e9e progressive : chaque nouvelle ancre s'appuie sur les pr\u00e9c\u00e9dentes, \u00e9tendant la zone calibr\u00e9e vers le haut. C'est le principe de l'\u00e9chelle de Jacob \u2014 un barreau \u00e0 la fois.<\/p>\n\n<div class=\"quote-bloc\">\n <p class=\"q-body\">Le grand tournoi sert \u00e0 identifier la hi\u00e9rarchie et choisir <em>quels<\/em> moteurs m\u00e9ritent d'\u00eatre calibr\u00e9s en priorit\u00e9.
