Hi, if you look at the payouts, 100 SP gets about 0.35-0.40 STEEM per week, plus upvotes could be about 15-18 cents (which is an additional 0.1 STEEM). The "bonus" upvotes are daily, or whenever you post, but subject to VP and systems all working.
Delegators also may win the Friday and Saturday free upvote or SBI share.

I think the total package means a higher income than most other sources - the only thing is we don't pay daily.

To put these numbers into context, an upvote (without deducting curation rewards) is currently worth about 0.415 STEEM per week per 100 SP.
