You say that as if it's a fact. You're on the wrong list to just make 
such an unsupported statement, there are people here who know better. 
Support your argument with authoritative references, such as these:

http://www.boulder.nist.gov/timefreq/general/pdf/192.pdf
http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=278607

http://tf.nist.gov/general/pdf/1379.pdf

Here's a representative quote: "When averaged past one day, the time 
deviation of the multi-channel common-views remains between 1 to 2 ns, 
while the noise of the single-channel GPS common-view drops below 1 ns 
for averaging longer than 2 days."
