As I noted also on the twitter thread for this, were I there, and
dishonest, (particularly were gobs of money on the table) I could easily
have permuted the bandwidth on both tests hugely upwards from a single
laptop by running continuous speedtests. But speedtests are not what we do
day in or out, and reflect normal usage not at all.

The 83% of people (experts!!!) that were wrong is ... mindboggling.

PS What wifi standard was at ietf? Is this still the old ciscos? The
headline bandwidths claimed for any version of wifi drop dramatically at
distance and with multiple users present.  So it might have taken a couple
laptops out of the thousand there to move the stats in a perverse
direction, now that I think about it.

Thank you for doing this experiment! While there are certainly also cases
were mass groupings of people totally saturate the underlying mac (more
than the perceived bandwidth - I have seen congestion collapse and a sea of
retransmits even in small wifi gatherings), the only number that seems a
bit off  in your test from a typical residential/small office is the
roughly 3.5x1 ratio between down and up. I am willing (for now) to put that
down to engineers doing actual work, rather than netflix.

I would so love to see more measurements like this at other wifi
concentration points, in offices and coffee shops. Packet captures too!!!!
