Daniel, We'd have to come to some standard definition of, "But even if 1% of users would reasonably be using a fully symmetric link to its potential..."
As I said, I have visibility into a large number of symmetric connections and without exception they'd fit well into a plan that offered upstreams with that had a fractional speed of the downstream. Now, keep in mind I'm not talking about 1/10 as a ratio here, but 1/5 would accommodate ~99.2% and 1/4 would fit ~99.9%. It's also important to note that all of these accounts are in the >25mbps down territory so their upstreams are >5mbps. What I see when I look at customer satisfaction ratings is a very strong correlation with low uplink speeds and a high satisfaction rate when we look at uplink speeds greater than 4mbps. What I don't see is an increase in customer satisfaction as upload speeds go past ~6mbps. Conversely, increases in customer satisfaction with correlate with increases in download speeds past ~30mbps before the correlation starts weakening.
