(Author here) To be fair, we are very rarely mobbing eight hours a day. Some of us come in earlier, some leave later, and you are always free to step out of the mob and go sit for yourself (even though we have been a bit bad actually doing that). I would say that we are effectively mobbing perhaps five hours each day, and the rest is spent thinking on your own, reading up on stuff, doing your own code experiments (bringing good results back into the mob) and doing all the other stuff you need to do in a day.
