For a while now I'm noticing a difference in the credits reported by BOINCStats and those shown on by my project account.

Currently my score according to BOINCstat is 4720, but Malariacontrol shows only 4177.

None of the other projects show this. The user ID and CPID is correct.

Thanks for your reply.

This situation has now existed for more than a week.
Also BOINCstats is showing a higher value (!) than the project page.

This situation has existed since BOINCstats exists, and same thing for any stats site in the world. Projects export stats only once a day, so there isn't much the stats websites can do about it.
