말씀해주신대로 15분 30분룰이 아니라, 
0분부터 30분까지 0%에서 100%로 리니어한게 맞는 것 같습니다!

정확한 룰에 대해 알고나서야 근거자료를 찾을 수 있군요 ㅠㅠ

### What determines how much of the curation reward goes to the author versus curators?
The payout split depends on how long after posting the vote was cast, using a linear function:
- If a post is upvoted the moment of posting, 100% of the curation award goes to the author.
- If a post is upvoted 30 min after posting, 100% of the curation award goes to the curator.
- Between 0 and 30 minutes, each moment that passes, more of the reward goes to the curator.

- At 15 minutes it's a 50/50 split.
- At 3 minutes, 90% goes to the author and 10% to the curator.
- At 27 minutes, 10% goes to the author and 90% to the curator.
