Sure. I'm talking about current_sbd_supply as seen on e.g. steemd.com. It is currently about 2.27M SBD. STEEM to SBD ratio is about 0.71 now, so total SBD supply is worth about 2.27 / 0.71 = 3.2M STEEM. This is about 1.9% of total supply of STEEM.

Now this number is significant because once this ratio exceeds 2%, a portion of authors rewards is paid in liquid STEEM. As this number grows, authors are getting less SBD and more STEEM, and at 5%, they receive no SBD at all.
