We have Sony, B&N, Kobo, & Apple as the big players. Then there are the people who have other readers. For Apple, I'm going with iBooks and none of the other apps.

Unfortunately, your math is based on an errant interpretation (feel free to blame my post's wording).
However, it looks like doing the math correctly still puts ePUB in the majority. (Assuming I have done
my math correctly at 12:30 in the am after a long day.
)
The article claimed 80% of
all ebook sales were in the US. They did not say 80% Amazon, but 80% counting
everyone selling in the US. I confused matters by pointing out the following: The poster who originally cited this information (and said "put up or shut up"), also made an errant assumption,
incorrectly arguing
as though that 80% belonged entirely to Amazon. No, that 80% belongs to all sellers in the US, be they peddling mobi or ePUB format.
Now, to get a more accurate breakdown of ebook sales, we can use your numbers and remove B&N's percentage.
Percentage of worldwide ebook sales in the US:
80%
Percentage of B&N US ebooks sales:
25%
Percentage of US ebook sales for Amazon and everyone else:
55%
At this point, in order for Amazon to maintain a worldwide majority for mobi format, Sony, Apple, Kobo, Google, Borders, etc., could only have sold 4% of all US ebooks!
How likely does that sound?
I think your summation works even better with these corrected values:

So given all of this, there is no way Amazon can be 80% in the US. The numbers just don't fit.

Indeed.
There is no way mobi/azw format can be a worldwide majority.
I believe this is known as "putting up," and the numbers -- though speculative -- put ePUB pretty squarely in the majority.
