Because end users will demand compensation and lawyer time for only 
getting 195Mbps on their 200Mbps service. 195Mbps is not 200Mbps.

I've seen operators over-provision services simply to quiet-down the 
noise, i.e., they'll provision 210Mbps for a 200Mbps service. We don't 
do this, but I encourage all of my competitors to do so.

The example I always give is that if there were no seats on an aircraft, 
it'd carry significantly more people than otherwise advertised.

We try hard to educate customers about how the higher layers eat away at 
the lower ones re: capacity, and that's just how the system works. There 
probably isn't a single man-made technology that offers 100% efficiency. 
So I'm not about to go out of business giving you the optical illusion 
that my corner of earth will make it so. In the end, it's easier to just 
let those customers go than spend human hours and money placating them.
