OK, I respect your judgement on that one.

I'm trying to figure out what our low bar is. That's why it starts with 
(and you removed in quoting) "At a minimum". If you think that's not our 
minimum, let us all know what is. But I think it's important to get it 
stated. What's the least we'll settle for, such that if we don't get it, 
we'll have to declare failure? I'm setting that bar at _some_ usability 
testing, with those resources. 

Turning it around, how about we also state a goal - what we're hoping for 
and realistically believe we could achieve. Could you (or anyone else) 
propose a sentence or two on that?
