Once you've submitted results and see the ranked results from your event it'll get updated in time.
A one-week wait is completely normal - not a big deal and I've seen worse. When the "top 20" rankings change was going through a couple years ago, new events weren't updated for almost a month.
I have occasionally seen events get missed (I believe it was a rejected submission without a rejection email), but once you see the results sans points you should be good to go. If you don't see the placeholder positions with zero points go up after a couple days, that's when you should probably contact Josh.
