Eponymous, I have never had SETI not count a WU unless it was a duplicate. I have resubmitted the dups after 5 to 7 days and they were accepted. I have even watched OK's proxy flush WUs, then within second I've checked and they are credited to my account. So, I am wondering how you are checking? If you use the main S@H page to check Individual Stats, or their team link, then I can understand your concern as those are update only periodically.
