Thanks for the observation, friend. I have studied a few journals on the internet that have followed the same steps I utilized but I noticed that those times, the market price of both assets were very close (Say, SBD = $3.2 STEEM = $3.32) or when SBD was around $1 or slightly below. I now have the understanding of putting the $1 peg of SBD into consideration on the Steem blockchain and the calculation has been edited. Thanks once again.
