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???

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

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>

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

about the perceived advantages of single digit differences in system latency
while ignoring the fact that the average human reaction time (call it organic
latency) is around 250 milliseconds. <br>
<br>
I guess you can argue that since we are inherently so slow we need all the
electronic help we can get!! <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>
