Statistical usage of journal downloads using EndNote's full text finder function: question re COUNTER stats

Hi guys,

A colleague has been testing COUNTER stats reporting of full text finder activity from EndNote & has posted that no COUNTER stats were recorded against the journals tested.

He used an obscure subscription title with no open access. The testing was onsite, within the org IP range. Multiple articles were downloaded using full text finder.

Can anyone shed any light on why downloads of subscription articles can occur but no usage is recorded on COUNTER?
