I think that's statistically incorrect.   The likely effect of what you 
propose would be to artificially discourage participation by people not 
living in large cities.

For me, pain includes those things but also includes things like the 
availability of food that is compatible with my diet.   And not just 
travel time but discomfort, which is nonlinearly related to travel time.

> Do we really want people who love to travel and couldn't care less where we go to be diluting the "pain pool" for the measurement?
I have yet to meet anyone who doesn't have a preference about where they 
travel.   But I think that letting everyone decide for themselves what 
is painful and whether the meeting location is an effective enough place 
to work to justify the trip, is much better than having one person 
unilaterally declare what the criteria should be.

The difference is that the chance of considering a small city as a 
location would be in proportion to the number of attendees from small 
cities.

But I also think that minimizing pain (however defined) is not the right 
overall criterion - it should instead be to maximize effective 
participation (of which pain is certainly a factor but not the only 
one).   Granted, that quantity is even harder to define than pain.   But 
several people have observed that the meeting venue has a lot of effect 
on the ability to get work done.
