Each post gets a 7 day payout window, during this window folks vote up and down, at the end of the 168 hours, the chain makes the calculations and sends your payout.

You might look at splitting up one long post into two or three smaller ones.
Nobody will complain about one post a day, but you start doing more and folks will notice.
