I think there is a reason that there aren't good definable terms. Awareness is awareness. How aware you are at any given moment can vary a lot, regardless of the state of consciousness. To me, your level of "lucid awareness" isn't a lucid dream, it's an almost-but-not-quite lucid dream. Trying to narrow it to 3 definable states boxes it in and might limit the potential of an experience, especially one that can vary a lot depending on the individual. Calling it "astral awareness" seems wrong in that you can have that level of awareness without being in the astral.
Just always shoot for clear, concentrated, focused awareness regardless of "dreaming" or "ap'ing" or "meditating", and even daily physical awareness (you KNOW some people are at 20% or less much of the time), and you'll be covered.
I agree AND I disagree.
I'll explain.
You're viewing these things as being external "experiences".
You're right in that consciousness can range ever so dramatically between each of these "levels", and as PR said, the 'scale' will never be accurate. But, I feel that, in a manner to teach what is happening to people who come here, I require some form of model. I mean, Robert Monroe and Frank Kepples models both worked wonders for me and has taken me far beyond anything I'd have even considered prior to them. However, for me, just saying "Conscious Awareness" didn't cut it... I couldn't say, "well you were 50% consciously aware, so you were lucid dreaming"... cause we both know that kind of scale would be even more meaningless than what I'm putting forth here.
Saying you have "Lucid Awareness" gives someone a better idea of what I'm referring to.
The main point of my original post, and where I disagree with you is where you say "
Calling it "astral awareness" seems wrong in that you can have that level of awareness without being in the astral.". You're saying that the "astral" is a separate place that you're "in". You're viewing it in that single sentence as somewhere to go to... where, I'm saying it's not somewhere you go... it's something you ARE.
You're not IN a Lucid Dream.
You have Lucid Awareness.
You're not IN the Astral Plane.
You have Astral Awareness.
even...
You're not IN a Dream.
You have Dream Awareness.
There is a massive difference between each of those sets of statements.
I believe that this is where the confusion comes in when people try to define these experiences... they're trying to define them in terms of external solutions. When really, all they need to do is look within for the answers. Look towards their OWN CONSCIOUSNESS.

Does a half-assed experience really need a definition? Lucid awareness = more work to do.
Yup, I certainly do believe that.
I'm one of those people that requires a 'definition' for my experience.

First, it makes it easier for me to place the experience within my own person... and secondly, it makes it easier to relate my experience to others wishing to either learn from it, or just simply understand it.
