Odd things shown on the statistics pages. If I sort the view by total credits for Theory or by total credits for Atlas and navigate to my own position, I see different total credits for Atlas. The difference is not big, about 4000 credits, but it is there. Does anybody else see this for their credits?

To keep away a high load from the DB server most of the statistics pages are taken from a page cache.
The cached pages are updated when a request is made to an outdated page or to a page that is not yet cached.
I don't know which timeout is set but the values can be different by a couple of hours.

Hello,

I also noticed a credit difference for me. (I only do sixtrack)
in the statistics by application, I see 175,065,281 for sixtrack and 6,008 for theory while in the total statistics I see 194,195,947
In 'my account' page, the total credit is 194,308,844
I do not know where this difference comes from but I think it appeared when merging the sub projects of lhc@home.

native Theory was a separate App in the stats up to last week.
Is this difference from it.

For me this is not as I have not done any native Atlas or Theory tasks. I did do some LHCb when it was available but the difference I am talking about is in vbox Atlas. I find it curious that by just sorting the values differently you get different value for a sub-project.

Since you are a member for more than 10 years :-) the total credits may include your results from other subprojects.
Maeax already mentioned Theory native but there were some more like LHCb or ATLAS before it was merged into this server.

Your Points for User-stats only:
20,596,761
When you look into the LhC@Home page for the User:
20,603,322
The difference is shown there also. Have no idea...
For me both are the same.

If I sort the pages by Atlas total credit, Atlas total credit for me is 6,214,458. If I sort them by Theory total credits, Atlas total credits show 6,208,371. So they seem to come from a different source? Smaller differences are shown also on Theory total credits and sixtrack total credits depending on sorting criteria.

As already explained the pages come from a page cache.
They are generated from the same source but at different times - sometimes a couple of hours while the account collects new credits.

Given LHC is storing this data, is there any reason why the data is not in the https://lhcathome.cern.ch/lhcathome/stats/user_work.gz file ?

The file is being generated and contains all the users but no data..

-bash-4.2$ zcat user_work.gz | more
