Actually, no it is not common sense. HTTP compression of XML can often
result in a payload that is smaller than the equivalent representation
in AMF. Why is that? Well, like any protocol, there are redundancies in
data, so even if AMF was the least verbose protocol known to man there
would still be opportunities for compression. If you are looking for
simply common sense, I'd stick with testing. It allows you to determine
the situation as it applied to your application as opposed to relying
on biased points of view.

It isn't a fair test if they don't take into account HTTP compression
or for that matter, alternate data providers.

It means that you have to assume that their benchmark is biased and
look at how it was arranged to best enhance their business case. Again,
the lack of viable alternatives being shown proves yet again that
benchmarks only serves the people who run the tests.

I don't see why not. Why would I want to use a product (Flash Remoting)
whose sole purpose to solve a problem I wouldn't have using HTTP
compression?

Not true; my tests have shown that in some circumstances Flash Remoting
is slower. It all depends on your application. Further, I have found
that even when Flash Remoting is faster it is not significantly faster,
which leads one to question whether the negatives of Flash Remoting
make it worthwhile.

Both arrays and structs can be large payloads as well.
