Do you realize that Olin was going out of his way to try to help you?
He suggested a way for you to learn more about LEDs, and you respond with "I
understand diodes completely", which is quite arrogant on your part.  I'm
not surprised that Olin responded with "Yeah, right".

There was nothing in any way belligerent in the post from Olin that
suggested ways for you to learn more.

Perhaps, but the point that you have missed is that the behavior of a LED is
more than just electrical, so your knowledge of diodes won't tell you all
about how LEDs behave in the real world.

As Olin said, data sheets can't really give you an idea of how bright a LED
looks (largely because human perception is not linear).  For example, does a
LED driven with 20mA look twice as bright as one at 10mA?  The data sheets,
and your understanding of diodes, won't answer that one for you.  Nothing
beats personal experience, and that was all that Olin was pointing out (very
politely).

You come across as being very immature.  Maybe you'd punch me in the mouth
too, for saying that, but it's just an honest observation.
