Rather curious this comment, checked and indeed if one chooses the 'All Projects' box in the My Projects page, AC@H is also selected and saved. Think it was not the intention i.o.w. an explicit opt-in was the objective, i believe. Time to drop by the web-tech if that is the correct functioning.

Other posts, including I believe one by knreed, have explained that the status 'Inconclusive' means that a quorum of 10 agreeing (valid) work units could not be established after receiving the first 10 completed back. Because of this, the server keeps on sending more copies to clients until it receives enough back that make up the 10 required *correct* results after which the 'Inconclusives' that are correct and agreeing have their status changed to 'Valid' with full (average claimed ) points granted and remainder 'not correct' converted to 'Invalid'.
Now stop the sob and be patient as that can take another day or whatever the deadline is of the extra work. Eventually if your job was 'invalid' you still get half the points of the others as token of appreciation
