I operate my site a bit differently, I purposely wait on average 48 hours to list submissions. The reason being is confidential. I normally take review submissions from the same 24 hour period (day). If you would like to be listed toward the top submit right after midnight.
Unless you are a gallery submitter. Galleries are listed at the end of the day's list.
Of course if you check
here you will find what I need most and raise your chances of getting listed near the top.
