? Question about Xrumer

Hi All,
I have a question about Xrumer which I havent been able to find a clear answer by Googling
That is what does the Part.Successful actually mean?
Has Xrumer actually posted on those links in the Part.Successfull?
Should they just be counted as fails?
Is it OK to have a high number in Part.Successful?
Can you clear this up for me?
Thanks

Edit: also what do the ones in the "rest" category count as?
