I think of pair programming like dancing. How much practice does it take to be able to dance with a partner before it's natural? More than a week, that's for sure.

I pair on all production code at work with only two other guys. I've worked with them for the last year. Together, any combination of the three of us is easily twice as effective as the fastest in our team. Something about the rhythm of the session, alternating roles, support when tackling boring parts, and the camaraderie frees us up to just get stuff done.

But, we work in a very complex domain that, a year in and many seminars by product later, we only barely are starting to grasp, with a large difficult to grasp system, sometimes solving problems just outside our comfort zone. It's not just CRUD and forms. So, maybe pairing is the four wheel drive of the programming world: uses more gas on the highway, but depending on your terrain, it might be the most fuel efficient way to get across a mountain.
