When Gwok Jing defeated the Cheun Jen Sect's 100-man Great Dipper Formation near the beginning of ROCH, it was considered quite a great feat. After all, none of the senior Greats who had preceded him had ever decisively defeated any of the Cheun Jen Sect's Big Dipper Formations.
Overall, however, was the 100-man Great Dipper Formation that Gwok Jing fought anywhere near as impressive as the 7-man Big Dipper Formation from LOCH? The seven original Cheun Jen Disciples were each far more powerful than any of the third-generation Cheun Jen Sect Taoists who manned the 100-man version (nobody better than Chiu Tze Ging in that formation). Did 100 of those guys using the formation equal or surpass the original Cheun Jen 7 Disciples using the formation?
