After the daily update, on my detailled stats page(here), I have a Recent average credit (according to BOINCstats) of 986 but the RAC chart show a different value (around 600)

After the next daily update, I have a Recent average credit (according to BOINCstats) of 1002 but the RAC chart show a different value (around 986)

There is probably a difference of one day between the two values

Sorry no one with a definitive answer has responded. If my memory is correct the BS-RAC is the average credit per day over 1 month. The RAC is exponentially decayed with a one week half-life.

Theoretically if you have a credit event every day on every project the numbers will be very close. However the time element and the way each deals with it makes them vary.

My problem is the difference between the BS-RAC shown on my detailled stats and the BS-RAC shown on the RAC chart.
The value of the chart is the value of the previous day and not the value of the current day.

It seems to lag one day, I have seen the same with me. I think it's a caching problem. All pages here are cached on the server and only created once every whatever hours. Same seems to be happening with the graphs, only a bit less often. I've seen my new data in the morning after the update, but often not in the evening of the update day.

I just tried my theory, and it worked.
In my usual german version there are new numbers, but old graphs, like I've sen them the whole day.
In the english version everything is up to date with me, they have just been created as pics with the english titles and current data.

As for the difference between RAC and BS-RAC: F.A.Q..

As for the charts not updated correctly: I added a more rigorous cache purge command.

Thanks Willy
It's ok now
