I'm trying to better understand. But once again I refer you to the
actual language at http://www.w3.org/TR/CSS21/fonts.html#propdef-font

"<em><b>All</b></em> font-related properties
<em>are first reset to their
<b>initial values</b></em>, ... 
<em>Then</em> those properties that are given explicit values in the
'font' shorthand are set to those values." (emphasis supplied)

I think that the language here is both entirely clear and dictates a
much better result (reset to initial value medium, then apply 70% to
medium) than what you say the cascade demands (ignore initial value
medium (don't actually reset font-size, because we pretend the initial
value is to be wholly disregarded when immediately within one construct
followed by an explicit value), and apply 70% to an inherited 80%). If
the way cascade is supposed to work is inconsistent with the above 15.7
language, then the 15.7 language needs changing.

Don't forget, font is special. Besides its purported reset function, it
also handles specially system fonts, totally ignoring properties they
should inherit.
