(Slight drift but still relevant)
When working on the radio in a congested uncontrolled airport, I was told, by an old salt of an instructor, to keep transmissions as short as possible. On way to do this while being more accurate is to not bother with the N number after your initial call.
Instead of saying "Piper 32779, turning 1/2 mile final, runway 7, at grassy strip"
I'd say, "white Cherokee, short final 7, grassy strip"
When scanning the sky I can find a white Cherokee quicker than some N number.
Just my opinion.
