I had always assumed the advertised speeds were likely (according to an unregulated definition), but not guaranteed. Even if the ISP gave me an SLA (maybe they did?), they couldn't make promises regarding the performance of any external network anyway. Maybe they should be required to report a sharing ratio in addition to bandwidth and latency within the ISP's own network. Any thoughts on how that would look, or what formula might make sense?
