Well, I beg to differ. Here's the calculation: https://steemit.com/steemit/@dragosroua/now-that-1-sbd-trades-below-1-steem-is-it-better-to-set-my-rewards-to-100-power-up
TL,DR as long as SBD is trading above $1, you may get a better deal by getting rewards 50/50, regardless of SBD and STEEM being at parity.
