I know I occasionally hit the limit, but I'd expect a decent level of service after hitting it.
I only use the 2MB service, so STM hits and I typically get failed pings and a transfer of 30-60KBPs on average. This data arrives in chunks one second apart most often. Typically this causes many timeouts, FTP falls over with uploading, ITunes times out connections etc. Basically when STMed, the service is hopeless and not once achieves the level of service they advertise.
