ok... so what is the percentage of these cases really?

How often will z be a factor in the routing decision?

A tenth of a percent of all 911 calls made?
A hundreth of a percent?
a ten-thousanth of a percent?
even less of a percent?

We're engineers who want to build an architecture as good as we can, but we 
can't take the case of the above percentages of a chance to steer our 
efforts. That's attempting to achieve too much without the imperical 
evidence of experience to make those decisions.

I'm a statistician by nature, and I deal in Standard Deviations, and 2 is a 
good number to work towards, 3 is excellent, and 5 is unrealistic. The 
percentages above are getting past 4 SDs and up towards (and past) 6 SDs.
