But this was a quasi-ideal number and in fact, in the goryakuso in 941, the emperor was not present and only eleven copies of the calendar were presented, and in the goryakuso during 993, Sakutantoji was not celebrated, no copies of the calendar was presented to the emperor and no chest arrived at the court (each according to "Honcho seiki").
しかも、それは半ば理想的な数字で、天慶4年の御暦奏には天皇の出御もない上に11巻しか奏進されず、正暦4年の御暦奏に至っては朔旦冬至にも関わらず、遂に頒暦の奏進が0巻で櫃の入場がないという事態となった（いずれも『本朝世紀』）。
