It is questionable whether the skill to respond to actual free offense and defense (the opponent resists, and the opponent's attack is unknown) is built solely through training in which the opponent doesn't resist and the opponent's attack is known in advance.
そのように、相手が抵抗しない、相手の攻撃は前もってわかっている稽古だけで、実際の自由な攻防（相手は抵抗する、相手の攻撃はわからない）への対応力が養えているか疑問。
