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.
