Because in PR, it isn't enough to represent 50%+1 of the voters.  You want
to represent as many as possible.  If we can get 80% of Floridians to
understand it, we can get even more elsewhere ;)

But seriously, the whole point of PR is that you don't just represent the
50%+1 in each electoral district, you represent as many as possible by
electing multiple members.

There's a difference between not knowing the answer, and not understanding
it.  I simply haven't read up enough to know which formula they use, but I
could understand the formula if I knew what it was.

A system can have many options and still be understandable, because the
likely consequences of each option are easy to understand.  A system can
have fewer options, and be hard to understand if the formula used to
compute the consequences is too intricate.

Sounds good to me.

That one will take some time to sell people on.  However, I'm all for
limiting the power of the executive.  Right now we have all the power in
the hands of a single person who acts like the office is his hereditary
birthright or something (oh, wait, it sort of is....), and we have a
Congress that acts like they're his White House Interns.
