http://setiweb.ssl.berkeley.edu/workunit.php?wuid=11286273 This is the workunit that did have 2 completed results (one was mine) but because of some other results with connection errors, was awarded 0 credits. I don't think is a good job from of results validation point of view. |

I > don't think is a good job from of results validation point of view. > Hi Sorin, Let's look at this WU, and remember the Quorum is 3 results. three results that the validator sees as close enough to be scientifically useful. Seti sends out the same WU to 4 people. then once for each failure that is reported back. This result was sent to 11 users, 2 never returned it, 1 had a computing error, 1 have a client validation error, 4 had a client downloading error, and 1 was Over-didn't need-done. Only two users finished this WU. it's hard for the validator to find a quorum of 3 with only 2 to work with. As a matter of fact much less than 1% of all the results sent every end up needing to be sent to 11 users. Also, I've done a study of this. Issue # of Count times %of total %done after issue cnt 4 105 61% 61% 5 23 13% 74% 6 16 9% 84% 7 18 10% 94% 8 8 5% 99% 9 1 1% 99.50% 10 1 1% 100% of all my sample I never had one that had 11 issues for example; the results that finished with 4 WUs occured 105 times, and constituted 61% of the results does this help tony |

So I guess it was just bad luck??? Hard to belive. I think that must have been something to do with those shut-downs... so many errors... and one is finished also but "validation error"? Thaks anyway. |

It was bad luck you were a part of the 9 others that had problems. Their problems caused your lack of credit. it shouldn't happen very often if that is any consulation. tony |
