I'm not sure if you've thought about this, but there is also a
difference between max_connections and maximum LIKELY connections.

It's actually an implicit assumption of the model Josh threw out if you stare at the numbers. The settings for work_mem are twice as high per connection in the Web+OLTP application cases, based on the assumption that you're just not going to get everybody doing sorting at once in those situations. I toyed with exposing that as an explicit "connection load duty factor", then remembered I was trying to deliver something rather than tweak the parameters forever. It may be a bit too aggressive as written right now in those cases.
