I'm curious about this. I see that lots of sites claim this to be the
correct approach to channel selection, apparently based largely on a
Cisco articlef rom 2004:

OTOH, some argue that these results are mainly relevant to enterprise
contexts, but less so to typical consumer environments:

http://superuser.com/questions/443178/is-it-better-to-use-a-crowded-2-4ghz-wi-fi-channel-1-6-11-or-unused-3-4-8

Everyone explains the theory as you've given it, and I suppose it makes
sense, but theory is no substitute for actual empirical evidence. I
suppose that for best results, I would have to benchmark throughput
across my links while on different channels. And even if I get better
throughput on 3, I'd still have to consider whether it's worth it, in
light of possible negative effects to my neighbors.
