I've been speed testing my shitty (Time Warner, yay) internet lately and am getting fully 50% of my 15m/s that I pay a whopping $80+/mo (hard to disambiguate between the 'packaged' cost with TV). I once got a Comcast rep to admit that they basically were unconcerned with providing anything which is at least %60 of the level that they advertise. Unless the entire company is both mentally and physically challenged I seriously doubt that this represents a "best effort" class of service. This is go-fuck-yourself service that a dive bar would be embarrassed by.
