Well, this is a practical consideration, not a theoretical one. Pan may
not support downloading multiple files at a time, but it does support
downloading multiple parts of the same file at the same time, and the
benefits are great.
As I posted on 5 July, using 4 connections resulted in a large file
downloading twice as fast as with a single connection, and using 10
connections was about 5 times faster. I even did the single connection
test last to eliminate any "news server caching articles and making later
tests faster" issues. So there's the advantage of simultaneous
connections. Maybe your test would be different, assuming you have a news
server that supports multiple connections. For me, multiple connections is
markedly faster.
I haven't repeated the test with 20 or 50 connections, but since GNKSA's
limit is 4, all I needed to do in order to show that GNKSA compliance is a
bug was demonstrate that any n > 4 produced a significantly better result
than n = 4.
