I was wondering how actually is comment's reward is counted in the system, so I did a little investigation base on my recent payout by comments.
First of all, you can find the comments payout under Author reward. This makes perfect sense to me as when we are typing a comment, we are essentially expressing our thoughts just like authoring a new post. For an informative and insightful comment, sometimes it could be longer than a post. So it is perfectly fine to take comment under Author reward.
The example above, I was receiving 0.240 SBD and 0.040 SP for a comment. From that, it is clearly not 100% SP payout we can conclude that comment's reward is following the 50/50 payout distribution.
As we know the SP is finalized by the market price of Steem after 7 days, we could ignore the SP and just focus on SBD. In STEEM algorithm, SBD is forever pegged to 1 USD despite how fluctuating the price actually is in the outer market(which is much higher than 1 USD now).
Since SBD is 50% in the reward payout, commenter take-home pay percentage is SBD in reward x 2 / Total comment reward. Apply the numbers into the formula, we have 0.240 * 2 / 0.64= 0.75.
In this example, I as the commenter took the 75% author reward just like how the post reward works.
With this comment, I got a total payout of $1.03 and the reward distribution is 0.516 SBD and 0.086 SP.
With the formula, we got 0.516 * 2 / 1.03 = 1.00. In this case, I as the commenter took 100% of the author reward.
You might notice that my reward come from self-voting rather than voted by the others, and this may be the cause of different reward percentage. Let's continue to have a look at another self-voted comment.
Actual reward is $1.12, I got 0.421 SBD and 0.074 SP out of the reward.
0.421 * 2 / 1.12= 0.75. I got 75% out of the total reward instead of 100% although this one was self-voted like the previous example.
Please enlighten me if I was doing any mistakes here.
