OK, I understand.

But what kind of solutions A and B do you have in mind that have a 100 % stretch difference ?

Once you start tunneling (i.e., map-and-encap or TE), then you pretty much can concoct any amount of stretch that you might want to imagine.  

Imagine an end-site that is dual homed in North America and Europe.  For a European destination, the European locator is preferred.  Suppose, however that when the European link to the site is down, all such traffic is tunneled back to the North American link.

This would trivially give you something like 200% stretch.
