Usenet search engine results take time to compile. Usenet works as a series of servers, you upload to one but it takes time to get those files to all the other servers (and there's no guarantee all the servers will accept them or may only receive part of the file). So one search engine may have incomplete for file 54, 192 and 193, and another engine have a different set. As you are uploading all the servers have different pieces of the pie and that's why things are coming up incomplete. Yet when you make the .nzb your server can possibly give back different incompletes or none at all. It's rare that pieces go missing, but retention is not perfect over the whole system. That's why PARs were invented.
Anytime there is a reset, the files will typically be considered as two separate uploads. Usenet search engines are taught now-a-days to spot similar names files and group them.
