Regardless of all that though, your reply completely ignores my point. Why is Steam so bad at estimating the download time? I even went into settings and specified I was using a 56k (modem) speed connection and those are the estimated times it still gives me.
It estimates ~30 mins when a realistic guess is around 7hr30.
Have you tried Steam's customer service?
Or is there a particular reason why you're trying to resolve a technical issue on an unrelated message board?
EDIT: Also let us know how long the download actually takes.
