There are a few distinctions to be made here.  For starters:

1. data vs. spec/format.  You're asking about comparing two XML *documents*
and then asking if one of them is a "well-done microformat".  That's not
quite an appropos comparison.  Comparing two format specifications and
asking if one of them is a "well-done microformat" would make more sense.

2. creating content vs. creating specifications.  These two are very
different.  Authors are creating content that uses microformats in all sorts
of ways, hand coding, tools, automatically etc.  OTOH, authors of
microformat *specifications* are creating them quite diligently, by
proposing problems spaces, doing background research on existing publishing
practices, and existing interoperably implemented specifications,
brainstorming, and finally making proposals and authoring a microformat
specification.

See above.

Often you may not even realize that a document is a using a microformat
unless you look very carefully at it.  This is one of the "micro" aspects of
microformats, they often involve very little change to existing content.
rel-tag is a good example, where literally simply adding rel="tag" to a
hyperlink to a tag page turns that link into a "tag" for that piece of
content.

Ryan's right that we are still figuring out some of the details, and thus
there is no precise mathematical equation for deriving a microformat.

And yes, your observations are right on about using the design principles to
determine set membership, or how much a particular format is a microformat.
 
In particular, somewhat as an exploratory exercise, I applied the principles
as an analysis tool to "RSS" as a format and came up with some interesting
conclusions.

I hope that helps.
