According to BOINCStats, here, on or about the 25th of March 2008 my team, B.C. BOINC, experienced a loss of about 125,000 credits. This coincided with Kueli2 leaving the team, however, I was under the impression that credits earned with a team stay as part of that team\'s total? Has something changed? Thanks in advance. |

Don\'t know about other Projects but CPDN credits come and go with the participant. "We have met the enemy and he is us." -- Pogo Greetings from coastal Washington state, the scenic US Pacific Northwest. |

... I was under the impression that credits earned with a team stay as part of that team\'s total? ... That\'s how it is with other projects, but not with this one. Credits are granted for each (new) trickle returned to the project, but BOINC was also granting credits for some computers in some cases. So some people were getting extra credit. To get around this, back in 2004 Carl wrote a credit script, which re-calculates all credits based only on trickles. (And an assumption, where trickles were missing but the final zip file existed, that the trickle(s) just went missing somewhere, but where still created). This replaces the granted credit with the correct value, initially \"on the fly\". However, as the projects user base expanded, this became a problem, so it is now run once a day. Therefore, it may be possible to get the extra credit, only to lose it again within 24 hours. The big problem, as you have found, is that credit doesn\'t stay with a team once a person leaves; it follows them on the next re-calc of the team credit. |

Since I admitted I am still alive and breathing on other sites ... If I may chime in here ... The historical reason for the credit staying was that SAH classic teams sometimes had one or two people that had large amounts of credit and they effectively became dictators on how the team was run. Do it our way or we will leave. was their threat. IN that teams were intended to foster some level of competition, this led to the \"newer\" idea that credit should stay regardless of the people coming and going. I am not making a negative diatribe against CPDN, just the historical observation. Much as I like my accumulation sometimes I wish we could grow up a little bit ... :) For me, the point of the credit is the personal accomplishment for each project and a footnote that \"I did that\" ... for others it seems to be a size contest, sadly. In the long run, I think those teams would have been better off saying good by to the people causing problems ... 10 small contributers can be far more important than one big one. |

Being able to take all your credits away to another team or start a new team with them encourages fickle team-hopping. Cpdn news |
