I did some in depth research a year ago and linked to all the Google resources there. See https://www.reddit.com/r/YoutubeCompendium/comments/aga8yl/how_youtube_copyright_claims_work_from_beginning https://www.reddit.com/r/YoutubeCompendium/comments/aga8yl/h... and also see the EFF link there. Specifically, https://support.google.com/youtube/answer/2814000 https://support.google.com/youtube/answer/2814000 mentions the courtesy period for anyone that's actually monetized and says the account won't go down at all if counternotices are sent. There's no courtesy period for accounts that aren't monetized (I.e. Not part of the Partner program). But of course if you're not monetized you have very little reason to dispute a content ID claim, since that also doesn't harm your account.
