it giving more sbd in this case isn't much of a glitch in my opinion, it just provides a way to stabalize the share prices into higher trading values afaik its not pegged down to a dollar its only pegged to not drop under a dollar, its only a way to measure a relative value of capital and shares, and it does that quite accurately even considering rewards, since shares are now handed out in a higher degree of scarecity when while they were worth 3 times less than sbd it brought the reward quantities closer together, and as that drifts apart the value drifts together, bringing steem up and sbd down and permanently making both relative sides of the market worth more to the outside world, creating that rising trend in combined value we see now.
