<font size="3">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...<br><br>
Anyone got a coupl'a mil $$ so I can but the equipment and conduct the
tests??? lol<br><br>

at what level can we perceive a difference in performance? In other
words, can we really perceive a difference between 7ms and 14ms latency?
I will not argue that large differences are readily perceptible (25
versus 250), but what about smaller differences. How large of a
difference does there need to be and is there a threshold below which it
does not really matter?<br><br>

Thus, your last statement is true, indeed!<br><br>

single digit differences in system latency while ignoring the fact that
the average human reaction time (call it organic latency) is around 250

I guess you can argue that since we are inherently so slow we need all
the electronic help we can get!! <br><br>

A lot of people are hung up on transmitter/receiver latency numbers, and
don't see the whole picture. This gives as good a fact based write
up as any I've seen.<br><br>
