Oracle DBMS / GC named user license count

Hi,
oracle recently did a soft audit in our organisation to find out what they call "real usage" of Oracle database licenses. To do this they counted all users of all databases, or, if the nr of Oracle usernames in a databases (DBA_USERS) was low, they looked at license high water marks. That led to a number of over 250 thousend named licenses, which is almost five times more than we would expect.
Doesn't sound like a fair count to me.
This has great impact on use of partitioning option and the rollout of grid control as these are linked to the database user count. What is the added value of grid control if we cannot use the packs because of the rediculous costs for it? Without Diagnostics pack we cannot set blackouts etc.

Btw, the product for doing this survey is called oracle satellite server.

What are your experiences with Oracle database/grid control license count?

Kind regards,
Andre
