Congrats on your growth and thank for the witness vote!
According to the report on HiveStats, I have a Curation APR of 0.61%, but I think there is a mistake here
Yes it is a mistake. When you power up, it calculates the previous curation rewards CR, that were based on a smaller amount of HP, and when compare to the now bigger amount, it distorts the APR. Example you had 1000 HP, and 7 days with 0.3 HP in CR daily. You power up to 5k HP, and now it still calculates 0.3 HP daily, but on much larger principal. It will fix itself in time.
Regarding CR advice I can only tell you to keep your voting power above 80%, ideally between 90% to 100%, but never 100% :), and don't vote on post older than one day.
I was sure it was a mistake, thank you for confirming it. I try to keep the voting power above 80%, as you said, I noticed that there is a daily 20% voting power regeneration. I didn't know that I shouldn't vote on posts older than 1 day. What is the reason for this? Thank you for the advice.
There is basically a mechanics (curation curve) that lowers the rewards for late voters after 24H. It used to be 5 and 15 min :) . This is something that initially was implemented to incentivize content discovery and rewards the ones who discover it early and voted early, but in practice it was botted a lot and not achieved its goal. Then it was pushed to 24H, to keep at least some incentive for early content discovery, but remove the advantage that bots had voting in 5 min window, and level up the game for humans :)
I didn't know that, now I understand. So now, votes on a post by different people within 24 hours do not create timing differences in terms of revenue advantage. Is it right to vote within 24 hours the only criterion?
Yes all votes in the first 24H on a post have same CR.
Curators will get higher CR, if there is more votes after the first 24H, so you might look into post that might do this, but honestly now I don't pay to much attention to this, as the difference is small, and just follow the first two rules, vote in the first 24H and don't go bellow 80%. This for majority of the post, if I see a post I think deserve some love I don't mind if it is older than 24H. Just know these things, and then it is up to you how to act, and observe how will it impact your CR.
Got it, thank you for your detailed explanation. I felt once again that I voted for the right witness
