Exactly!

The issue is that 95% systems produce different answers on the same data 
set when using the same algorithm simply by altering the relative phase of 
the two 95% measurement systems. The only way to get the two systems to 
produce the same answer is to get them to synchronize their measurements in 
time. I like the idea of the visible 'pulse' to allow the customer to sync 
with the provider. Unfortunately I'm not sure I can see what the IP meter 
pulse equivalent would be!
