Why are you dividing it by 2?
Author rewards are 75% SBD and 25% STEEMPOWER so divide it like that!
Just to reiterate my main point, you say the author reward is about 75% SBD right now, that doesn't mean you use 75% instead of 50% when calculating the SBD part of the payout!
Yes - it means exactly that! Author Rewards = Rewards the author is getting paid out.
