That may be the minimum loop time, but it's not the minimum perception time.

I suggest you imagine playing a keyboard and hearing the music that results.
When playing music .25s slop would be considered more than disastrous (I play
keyboard.) It would be fatal. Think about writing the software to handle an
electronic piano keyboard. I don't think you'd never sell any with a .25s delay
in the responses.

When I use front panel keys on an instrument (and yes, I also write the software
for such instruments), 1/4 second delay between hitting a digit, let's say, and
seeing that digit appear on the display is often unacceptable to me as an
operator. I've test this kind of delay on myself, and it was not pleasant.

Yes, I could live with it. But I might not buy that instrument, again.
