I noticed, that the credits of BBC CCE and SIMAP are always wrong. 
My site updates each project once every 24 hours. Other sites update more frequently.
The project sites in its turn do update their stats at some time.
ones once a day too , others some more frequent ...
This seems to be a timing problem 
eg: project site a updates once a day ... say 23:30 UTC
mundayweb updates once a day too ... , say 23:29 UTC
*Clearly the stats of project site a,  on mundayweb, 
  will ever be of  yesterday  
However IF mudayweb updates was at 23:45 UTC
project site a on mundayweb will shown stats as up-to-date 
as of other stats sites  that do more frequent stats updates
So, this is a simple mater of finding the UTC time at which each project
site generate their stats ...
and then 
programing mundayweb crontab to update that project stats 1 hour later
PS: The time at each project site generate their stats, 
is expected to be different to each project
