Right. The arm operator and the IVA crewmember need to be separate
people, because they have to pay attention to different things. So the
minimum crew size for a dual-pair EVA flight is six.

Errr, ummm, that would be four assuming the non-EVA pair would be IVA and
arm
operator. They would have to be cross trained but what's wrong with EVA
today, arm operator tomorrow?

do you really want the person working the robot arm to be the same person
that worked themselves to the brink of exchaustion theprevious day doing an
8-hour EVA?

Didn't think so. Oh, and with a crew of four, one of each pair would have to
be fully-trained shuttle pilots, so now they have *three* jobs to prepare
for. *Bad* Clark, no cookie...
