Paul, I noticed some of the people posting edits/fixes (spelling, line break) got down-voted, and others wanted to argue/disagree about it. Silly. Personally, I like having others point out my mistakes; it's the best way for me to know about and fix them. With this in mind...

I hope no offense is taken. ;)
And now, the more important stuff...
As you know, the terms often control the discussion, so kudos for your notes listing the various terms, i.e. "Super Angels" "Mini-VCs" and "Micro-VCs." Some have balked at the use of the adjective/term "super" as misleading, but the terms typically used, and their corresponding definitions don't have distinct lines. A potential resolution might be using the term "archangel" for the investments/investors beyond the typical "angel" round? Anyone fluent enough in English to know the term "archangel" will understand the implication of it being greater than "angel." --It's just a thought.
Another thought would be to break down the classifications by their most defining aspect, namely amount of capital. The lines will still be imperfect, and you have a better grasp of the numbers than I do, but the language would be generally more clear. I was thinking something like this:
seed: angel: 30,000 - 150,000
archangel: 150,000 - 1,000,000
vc: > 1,000,000
That would classify YC pretty much as you describe it, namely, as a "seed fund," or better said, specializing in "seed round funding." At present, I still not convinced my little idea above is any better than the currently confusing status quo, but at least it's an attempt.
EDIT: Uggh! Fix line breaks ;)
