My point is.. they did not use the slide rule to design the actual boots.
they have used the slide rule to predict and calculate the working environment for the entire space EVA and moon surface program.. To what the boot, helmet, suit, gloves, coupling, the LEM, the CM and everything else had to work in.
The temps and pressures were not uniquely calculated for just the boots, everything else had to live in that same environment
So once they had done that.. and went about to designing the actual boot
the slide rule no longer was required.. All they had to do is fabricate, and test, and test some more, then retest and you don't need a slide rule for that...
tape measure perhaps.. and pressure and temp gauges for the test.. but not a slide rule..
If you still have to calculate requirements at the time you start designing a boot.. yer just wasting time.
