Seems a little harsh considering how long it takes to build them up...

Ideas why anyone?

As far as I am aware credits are never deducted.

You will need to provide a little more information for anyone to comment.

BOINC Stats page: [url] https://boincstats.com/en/stats/-1/team/list/0/100/United%20Kingdom#139[/url]

Shows over 1 million points deducted from overall score. There are others with deductions but nothing like that number....

It's taken me years to hit over 17 million, there must be a sound reason?

The -1,014,530 is under Credit/Month, means that the team is earning 1,014,530 fewer credits per month than it did the month before (which will happen if someone with a RAC of just over 30K leaves.)

Total credit will not (or should not at least) ever decrease.

wow, my bad.....that makes perfect sense.... Thanks for putting my mind at rest :-)

So after further checking, it seems that yes the points have actually been deducted. The team was in 134th position and you can see has dropped 5 places in the BOINC stats.

I don't believe I am wrong about this. but open to proof of otherwise. I would just like to understand why to avoid recurrence.

The daily weekly and monthly stats shows actual not relative scores. In conclusion, points are being deducted.

Thinking of a reason, I had a machine that crashed a few weeks back and so all work units on it in progress and scheduled were lost. Would that have led to a deduction?

I can't think why as the points would not have been allocated for work in progress and not yet done but I have no other explanation.

You should have linked to this page, https://boincstats.com/en/stats/-1/team/detail/183361794/lastDays
Seems points declined on 2018-06-29.

It's a problem with Climateprediction.net (CPDN), which becomes apparent if you look at your team's BOINCstats Project List. The error occurred on 28 June 2018, and it's affected other teams too.

CPDN has been having system issues lately. There are some threads in the BOINC Projects message board that allude to it, and there's a tweet on the project's main page.

Best point to https://boincstats.com/en/stats/-1/team/detail/183361794/projectList which shows the credits are deducted from CPDN, which is correct because that project did a whole reboot and still has all kinds of trouble.

See Zero / Negative Credit on the CPDN forums.

Thanks for the explanation, makes sense now.

I didn't think it was me as I'm the only member in the team right now and using 2 laptops to crunch until one died at the end of June.

It was interesting to look at the performance of my old laptop as it degraded over a relatively short time. It was an i7 with an Nvidia 860m running 24-7 and not used for anything else.

It would maintain around a 12/13k points average on its own for a couple of months then quickly degrade to around 4k points average. I would then recover Windows for a fresh start [losing all the work units] at which point it would hit 12/13k average again [cycle / repeat]

No amount of cleaning the machine [ccleaner / disk clean / defrag / reboot / registry clean etc.] would move the stats up, only a reinstall.....

I wonder what causes this and if others notice the same issue? It maybe as it was not used for anything else it was more noticeable?
