マッケンジーがDr. Phil Cheethamの研究を紹介しながらROCとショット精度には何の関連もないことを語ってる
there is currently no evidence to suggest that players with lower RoC hit more fairways or hit their approaches closer to the hole.
For example, in his PhD Thesis, Dr. Phil Cheetham found no relationship between shaft twist speed and driving accuracy in a group of 70 PGA Tour players.
