I don't know. Maybe ask them? ;)
Seems like the pool of funds steem uses to pay out the 7 day period needs to build up so until that happens, rewards will be lower. But yes, as it builds up I'd imagine the rewards will go up, but I don't think it will catch up to what it was before since new posts will be created which are also taking rewards.
Keep in mind that every day the same amount of Steem is minted. After 7 days you have 7* amount per day to be distributed over 7*daily posts/comments, so netto effect should be that posts value of posts done with pending payout will get same value as they had before HF17/18 upgrade. Apparently the calculations are now done on 30days, hence normal should be then after 30 days, hence the 3% (not exactly, since my interpretation is 1/30 = 3,3333333% @abit mentioned in his post (https://steemit.com/witness-category/@abit/abit-witness-upgraded-to-0-18-1), that is my logic.
Anyway, will ask further clarification to @abit.
Ok posted this question to abit, lets wait for his answer...
Ok, since in other posts I see different information (like here: https://steemit.com/steemit/@lukestokes/don-t-hold-back-your-best-content-while-rewards-are-low), I like to get an example for you from my own post, posted just before the HF17/18 upgrade.
The post had a value of 4,20$ before the upgrade with a 24hrs pending payout. After the upgrade the value jumped back to 0,03$. The post will now be paid out after 7 days. Will the value be up to 4,20$ again without any new votes coming in, and also assuming it would have stayed at 4,20$ (not taking into account more posts coming causing the value to change because of the re-distribution), also assuming my previous assumption, every day same number of posts/comments etc as we have more or less every day prior to the HF17/18 upgrade (and of course per day these numbers changes in reality, but lets assume that will be fixed for coming days).
In the end my question, as from so many others, that I like to get 100% clarity on: will the value of posts prior to HF17/18 upgrade, in the end have the same value after the new pay out term of 7 days? AND will posts done today get same value as if same post done in 7 days from now under the exact same conditions? and what about when posting after a month, 30 days, again under the exact some conditions?
