Thank you so much. You have given me the answer I was looking for, and reading in FAQ of steemit, but I didn't find it till now. I was wondering why the 50% of 75% wich represent SP is so less compared with 50% represented in SBD. Now I understand. The SP is calculated from $ devided at the rate of Steem. Great job. I realy apreciate it. I'm happy I read your post.
