Below is a close-up linear chart showing a drop of SBD payouts when the SBD stability code kicked in, however, a few days later SBD payouts rose again (but not to their previous levels, the rise coincides with the correction down of the STEEM price around the 24th), the STEEM payouts dropped too later on, probably due to the formula used to calculate the SBD stability payout percentage and the state of the market prices.
