 - 점수 계수가 보정된 채보와 복수 기수 카드의 보드 보너스는 이전 버전과 계산 결과가 달라질 수 있습니다.
 - 현재 실측 점수 계수가 등록된 채보는 일부입니다. 계산 정확도 향상을 위해 대부분의 악곡에서 실측값 제보가 필요합니다.
-- 실측값 제보: `[제보 링크 입력]`
+- 실측값 제보: [Google Form](https://docs.google.com/forms/d/1bShzsxNN-iTk0uU3RfMfmLkYXYmUTmIWMmCtQmfl_Ik)
 - 연결 카드 최적화는 결과를 확인한 뒤 적용할 때만 사용자 데이터의 배치를 변경하며, 적용 직후에는 이전 배치로 복원할 수 있습니다.
