However, it can't be denied that the content of Kangakue was gradually formalized, and even in the Kangakue held in 1071, which is said to be a Kangakue in which old customs were revived, an event was only held for half a day, from 2 p.m. through 10 p.m., even though originally, it should be held for three days (actually, two days) (it is believed that as the formalization advanced, the period and content of Kangakue was reduced, too).
だが、次第に内容が形式化していった事は否めず、旧儀が再興されたと言われている延久3年の勧学会でも3月15日の未の刻より亥の刻までと、本来の3日（実質2日）がかりの行事がわずか半日で終了している（形式化が進んだ以後の勧学会は更に時間も内容も削られていったと考えられている）。
