Have you ever noticed that if you have a PCGS coin in your NGC Registry Set, the Census numbers shown are for NGC coins in that catagory?

I wonder what it would take for NGC to show the current PCGS Population Census numbers for PCGS coins. They already have to link up with PCGS to verify certificate numbers, so it seems to me that they could work out some agreement with PCGS to include the census numbers too. It may be a little bit more complicated than I make it out to sound, but I sure would like to see the right numbers.
