Zero fret height is defined as,..... the depth of the fret slot that
equals the same point as the
height of the fret ahead of it.


Okay, since class is apparently in session:
NOt sure I understand you exactly. Is the bottom of the slot in the nut
exactly as high as the top of the 1st fret?

You have to go a little deeper... when you fret a string,
the string doesn't just break over the fret; it has a tendency
to be lifted up, caused by the steel wire's natural stiffness,
or resistance to bending. This gives a little extra lift to
fretted strings, as opposed to the nut or bridge, where
they get to go straight across.

When you set up a guitar, you start with the first fret... the
height of the nut, etc should keep the string from buzzing
on the first fret when the open string is played; this is basic.
Add a fret, then finger at the first fret... now you have the
same situation, you want the next fret to be the exact height
for no buzz. The easiest way to set this up is to have a
perfectly flat fretboard, with the nut set barely higher than
a fret, and the bridge adjusted up until you get no buzz...
effectively, the angle of the fretted string remains constant
since the frets are far from the bridge (if you were fretting 2"
from the bridge things would be different!).

Does this mean that you must have relief in order to prevent buzz? Or am
I missing something?

'Relief' allows you to have your cake and eat it too... the above
scenario is an approxiamation, the angle really does change,
noticeably so as you go way up the neck. The way to have
your cake and eat it too is to have the neck bow in slightly...
now you have low first frets and lower end frets than before.
The string also has more room to swing, which means you can
hit it harder without buzz, and you get lower action up high.
