User based, long duration tests seem fundamentally flawed. QoE for users 
is driven by user expectations. And if a user won't wait on a long test 
they for sure aren't going to wait minutes for a web page download. If 
it's a long duration use case, e.g. a file download, then latency isn't 
typically driving QoE.

Not: Even for internal tests, we try to keep our automated tests down to 
2 seconds. There are reasons to test for minutes (things like phy cals 
in our chips) but it's more of the exception than the rule.
