Bill, that is an empirical question -- one that could be tested in 
the lab.  However, I am convinced that your implication is 
correct:  the difference between 7 ms and 14ms is probably not 
detectable by anyone.  The fascinating question is, where is the mean 
cut-off time between non-detectable and detectable delays...

Anyone got a coupl'a mil $$ so I can but the equipment and conduct 
the tests??? lol
