Hoi,
These numbers provide a snapshot. They do not indicate how these numbers 
relate to the overall number of Commons and they do not indicate if the 
problem becomes worse. The argument was that this trend should be seen 
in percentages, this is not provided by the data. What was the average 
time that deleted pictures were on the system ??

This policy is very much going to happen as you lot seem determined to 
push it through.. Never mind ..

What I would be interested in knowing is the usage in percentage of 
Commons pictures used in articles per project.

Thanks,
