Dans les 164 parties retenues, la vitesse m\u00e9diane par partie est de 95 \u00e0 98 % et aucun coup ne retombe au palier de 60 % ; seules trois parties, vers 11 h 15, montrent un creux bref \u00e0 ~70 % sur deux coups. Deux nulles de 15 coups, jou\u00e9es dans le livre, n’ont pas de mesure exploitable. Avant nettoyage, l’estimation provisoire \u00e9tait de 2426 \u00b128.<\/p><\/div>\n\n<h2 class=\"sect\">6. Conclusion<\/h2>\n\n<p>\u00c0 240 MHz, le Mephisto Genius 68030 London atteint <strong>2414 \u00b128 Elo<\/strong> sur 164 parties, confirmant que le programme de Richard Lang sur 68030 sature rapidement avec la fr\u00e9quence. Le gain marginal de ~18 Elo par doublement contraste avec les ~49 de The King 2.54, dont l’algorithme exploite bien mieux le temps de calcul.<\/p>\n\n<p>Ce r\u00e9sultat est coh\u00e9rent avec les mesures ind\u00e9pendantes du ChessGenius Exclusive ARM \u00e0 300 MHz, et explique pourquoi les versions modernes de ChessGenius sur mat\u00e9riel rapide ne surclassent pas aussi nettement qu’attendu les anciennes versions lentes.<\/p>\n\n<div class=\"box\"><span class=\"box-titre\">R\u00e9sultat d\u00e9finitif<\/span>\n<p>Gauntlet clos le 25 octobre 2026 \u00e0 14 h 57 : <strong>2414 \u00b128 Elo<\/strong> sur 164 parties \u00e0 vitesse v\u00e9rifi\u00e9e. L’incertitude reste de \u00b128 : r\u00e9duire l’\u00e9cart-type d’un tiers demanderait environ deux fois plus de parties.<\/p><\/div>\n\n<hr>\n<h3 class=\"ssect\">Sources<\/h3>\n<ul
