Upset Percentage

[AndyBare]

To rephrase, and hopefully garner some more conversation/thoughts, here are the outcomes and calculations.

Each field has 4 Quarterfinal pairings (Q), 2 Semifinal pairings (S) and one Final pairing (F) for a total of 7 pairings.
With 8 division fields and Einstein, we have 9 fields total, with 7 pairings each, for a total of [edit fixed: 63] pairings.

Pairings with upsets:

Alliance 5/4 - Q - 2
Alliance 7/2 - Q - 3
Alliance 4/1 - S - 4
Alliance 4/3 - F - 5

Above you see that 27 out of those edit [63] pairings were upsets, giving us an upset rating of 42.8%.

So has anyone in FIRST ever seen anything quite this unpredictable before, or was this the most unpredictable Championship you've seen?
Why?
