I'm sure that is correct. BUT 😉 on top of that there's some mechanism I haven't been able to figure out yet. Look at my wallet, I haven't received anything except for 0.003 from curation. And I've had some cents before and after 7 days (just for a short while after and then they disappear). And I noticed some of your past posts showed 0 reward even with 4 votes, should entitle to 1 cent at least. It seems like there's a cutoff limit and nothing gets paid under 0.02$ (one of my 0.02$ became 0 too, though). Above that the payments get processed and you get what ever you deserve, which was 0.003 SP in my case.
Anyway like I said, I haven't been able to find anything about this and this is just something I have noticed.
Edited the post above.
