The delay isn't what's causing this. In my article I wrote
It tracks the value of Steem denominated in real US Dollars
The key is real US Dollars. When the Steem blockchain pays out a reward, it doesn't know that SBD is trading so high. All it knows is the value of STEEM in USD, and it assumes that SBD is worth $1. If SBD is worth significantly different than $1, it throws everything out of whack.
Oh as in it tracks the value of Steem and not SBD, that seems counter intuitive however it does also seem that in a real sense SBD is more liquid than Steem due to SP being directly linked to Steem, I would suggest both this and the current market cap are giving it the extra value in the real world markerplace. Also tied in with the idea that promoted posts burn SBD from circulation and therefore the more use of this function in the platform the higher value of the currency. Can you tell me what the print rate stands for in steemd.com? I cant seem to find anything that describes its function. Thanks!
Hmm, you're talking about sbd_print_rate? 10000 means 100%, so I'm guessing that means that right now all the liquid rewards are paid as SBD, not STEEM. It's been that way for a number of months.
I don't know how long you've been around so I don't know if you'll have seen this, but when the market cap of STEEM gets too low relative to SBD, the system starts paying liquid Steem instead of SBD for author rewards. It's a safeguard against there being to much SBD for Steem to safely back it, but it hasn't kicked in in a long time.
