[NSRCA-discussion] S.bus

[Dave]

I believe the NSRCAAFAPSAHITIRCAF has been directed to join NASA in their
efforts of cultural unification...

Sounds like a mission for the NSRCAAFAPSAHITIRCAF (NSRCA Academy For
Advanced Pattern Studies And Human Interfaces To Improve Radio Controlled
Aerobatic Flight).

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

The next question then becomes, 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?

As a Psychologist, I agree with you, Bill.  As an R/C pattern jockey, I will
only point out that the electronic latency is ADDED TO the wet-ware
latency...

Thus, your last statement is true, indeed!

I am amused by discussions about latency. We have long discussions 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. 

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

There is a great article on latency here:

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.
