I'm a Fed engineer and spent a 4 mo. assignment on an integrated team with Pivotal pairing exclusively. It was a long 4 months for me. There was no "zone." I'm not built for pairing.
Yeah, because everyone knows that you have to pay less wages when you have two people do the job of one.
If you think pair programming is a good idea you are just at the bottom of the industry.
Can I come live in this fantasy world you found yourself in please? You're gonna need to provide some SERIOUS proof for a claim like that...
