The statistics certainly *should* be used when provisioning aggregate
resources.
But even if 1% of users would reasonably be using a fully symmetric link
to its potential, that's a good reason to at least have such circuits
available in the standard consumer mix, which they aren't today.

Daniel,
Well, I wouldn't call using the mean a "myth", after all understanding
most customer behavior is what we all have to build our business cases
around. If we throw out what customers use today and simply take a
build it and they will come approach then I suspect there would fewer
of us in this business.
Even when we look at anomalous users we don't see symmetrical usage,
ie top 10% of uploaders. We also see less contended seconds on their
upstream than we do on the downstream. These observations are based
on ~500k residential and business subscribers across North America
using FTTH (mostly GPON), DOCSIS cable modems, and various flavors of DSL.

It isn't that most, or even many, people would take advantage of
equal upstream bandwidth, but that the few who would need to take
extra measures unrelated to the generation of that content to be
able to do so.
Given symmetrical provisioning, no extra measures need to be taken
when that 10 year old down the street turns out to be a master
musician.

This is true in our measurements today, even when subscribers
are given
symmetrical connections. It might change at some point in the
future,
especially when widespread IPv6 lets us get rid of NAT as a de
facto

How about this? Show me 10 users in the average

but I don't think you want everyone accessing that
anyway. The truth is
that the average user does not create content that anyone
needs to see.
This has not changed throughout the ages, the ratio of
authors to readers,
artists to art lovers, musicians to music lovers, YouTube
cat video creator
to cat video lovers, has never been a many to many
relationship.

And when you expand to several billion people creating

you need a *huge* pipe down.
