Pardon me, ever heard of dead volume? There are some reasons why we only use
20%, as you say. By the way, this percentage is suspiciously close to
atmospheric %O2.

This is my xx-th posting in this thread in 45 minutes. A lot of the *facts*
;) irritate me because they conflict with my physiology books. Just now I see
this is a thread cross-posted on comp.ai,sci.cognitive. Explains a lot. I refer
for further information on CO2 pbp to any physiological handbook.
A man conducting a gee-whizz science show with fifty thousand dollars' worth of
Frankenstein equipment is not doing anything scientific if he knows beforehand
what the results of his efforts are going to be. A motorcycle mechanic, on the
other hand, who honks the horn to see if the battery works is informally
conducting a true scientific experiment.
