The rewards are allocated so that 75% of the payout goes to the author of the post/comment, and 25% goes to the curator.
Of the 25% that goes to the curator, that portion will be split between the author and the curator if the curator votes within the first 30 minutes. The split of the 25% between the author and curator during the first 30 minutes is calculated linearly based on the time the vote is cast.
If a post is upvoted the moment of posting, 100% of the curation reward goes to the author.
At 3 minutes, 90% goes to the author and 10% to the curator.
At 15 minutes it's a 50/50 split.
At 27 minutes, 10% goes to the author and 90% to the curator.
If a post is upvoted 30 min after posting, 100% of the curation reward goes to the curator.
thnx ! Does resteeming cost some sp or is it free ?
Nothing costs anything except for buying STEEM/SBD. STEEM Power is like holding shares of a company which only serve its shareholders. The amount of SP you own is the amount of control you have on the platform. With your stake you can do anything.

You can vote until your VP is depleted and you can use the platform until your bandwidth is depleted. None of these will cost you anything.
