Thank you for reading and comment. I aware the "estimated payout" can be changed according to Steem/SBD price during the 7-day payout period. What I don't understand is that "after" 7 day when the "pending payout" already changed to "past payout", the figures shown in the "past payout" does not match the figures shown in the author reward amount (inside wallet). 10.05 SBD vs 7.6 SBD, the difference is more than 20%.
