with another rest period scheduled in there some
time of several hours . This would be satisfactory .
I felt we were really productive when we were both
up . I would like to see periods of time in the
day where each of the guys are up at the same time ,
and doing actual experiments and work . When you
are working together · like that, it seems you are
complimenting each other,and I think you get more
productive observations . Some of the experiments
require two guys. D-6 is going to require two
guys~ D- 9 requires two guys , and to adequately do
it to get the pictures we want,you just need two
guys up .
Let me modify that position of mine even further .
If you scheduled a six-three and then the other
guy with a six-three that would leave you six
hours up together everyday . I think that might
be adequate .
You should also always try to schedule your eating
periods so you aren, t" eating during this up time .
You should schedule your eating when the other
guy is sleeping.
Right.
