One can be quite certain that a user will not wait for 3 days for a web page to load without being certain whether the user will wait 30 seconds, 1 minute, 3 minutes, or even 1 hour.

It’s very easy to call 3 days untimely in such a case. It is very hard to draw a clear line among the lower values.
