Both @Home and RoadRunner performed extensive load tests during trials of the cable modem system before roll out deployment in several cities. As you can imagine, the results are closely guarded, proprietary information to those companies. But I can assure you that they know exactly how their networks perform under various load conditions, stresses, and configurations. Numerous architectures were studied, most of them having to do with various numbers of homes passed (percentages of penetration on a 500 homes passed node vs. 2000 homes passed node). They know when it is appropriate to split a node and how much that costs within $0.50 to do that. Of course, that is all based on test "models" and so any individual node may perform much better or worse depending on the loading, architecture, and costs in any particular cable system. Many variables involved, which explains why there are cable subscribers reporting very slow speeds in some instances. Suffice it to say that early RoadRunner tests stressed a system to test its limits and were able to load it to the point that speeds were in the single digit kilobit range. The penetration level that created that condition is not known to me, however, but I know they know, and they're not talking.
