Steem Curator Reward System

Something came up in our MinnowSupportProject discord channel at PALnet earlier which seemed like a really big grey area for SteemIt users. This confusion was regarding the separation of rewards between curators and authors when a post is published.

SteemIt posted an answer regarding the dispersal of curation rewards in their FAQ but when we went over it; we found it pretty confusing so I'm going to attempt breaking it down for anyone who is curious or is confused about it still.

In order to understand the breaking down of curation rewards, first you have to understand that of the post value, authors obtain 75% while the other 25% is split between the author / curator. For this post, lets focus on the 25% aka the amount of rewards possible for curators to obtain.

To make this simple, let's start from the back and move towards the beginning. When a post has been live for 30 minutes and a curator decides to upvote it, the ENTIRE portion of that 25% goes to the curator PERIOD. If any curation rewards are gained on an upvote that has been made past the 30 minute mark of post publication, those rewards go straight to the curator.

The next "reward bracket" is what I'll call it, is the post-27 minute curator reward. In this bracket, upvotes made by curators between 27 minutes and 30 minutes past the time the post has been made live, will be split 90/10. Of the available 25% up for grabs to authors and curators, 90% goes to the curator and 10% goes to the author.

Following that will be the time period between 15 minutes and 27 minutes of when a post is created. When a curator decides to upvote a post during this bracket they are able to receive 50% of the reward while the other 50% goes to the author. AGAIN, this is 50% of the AVAILABLE 25% curator post rewards that you can possibly obtain.

The smallest bracket where curators are able to obtain rewards is the period between 3 minutes and 15 minutes after post publication. In this bracket when a curator upvotes, they are able to work towards 10% of the total 25% curator rewards while the author receives 90% of it.

Finally, there is the period where I like to call the author bracket. During this time or right when an author posts to 3 minutes after the post has been up, the curator receives no possible curation reward. In this bracket, the entirety of the upvote in the available 25% curation reward is given to the author and the author only.

Now that you've gotten a description about the curation reward brackets you also have to understand the second part to curation rewards. This understanding is the realization that upvoting a viral post before someone else, will allow for more curation rewards to be dispersed to your account. From my understanding, when curator A upvotes 16 minutes after the post has been made live and curator B upvotes at 26 minutes when the post has been created; curator A will receive a higher curator reward.
Why does SteemIt do this you ask?!
I once pondered this question myself but I realized it really is a great system to contain quality content separate from spam. If curator rewards were a flat rate and it was a first come first serve system, spammers all over the platform would be upvoting new posts as soon as they go up every second. They wouldn't be taking the time to read quality content provided and figure out if it is worth upvoting and spreading to other fellow Steemians. Essentially SteemIt's curator system allows for those who upvote carefully and qualitatively an increased chance for rewards.
Thanks for reading as I hope I've gone over the general breakdown of the curator reward system. I may have missed some key ideas or completely misunderstood the system so I'd love for feedback in order to revise my understanding!
