I think cable companies should state the minimum and maximum speeds. It might take a while but if they survey each node they can tell how slow people and how fast people are going on each speed tier.
Then when you call the agent would say:
"ok bob, you are on node 12569. We just finished testing the speeds on that node last week, for people who choose the blazing fast internet package for $75/month, the minimum speed over a 3 weeks period was 20 mbps down and 3 mbps down, the maximum speed was 50 mbps down and 10 mbps down thus you can expect an average speed of 35mbps down and 7 mbps up."
See that wasn't hard, was it. Just may take some work.
