Personal O2 Toxicity Concern question..

[Charlie99]

Dr Paul Thomas once bubbled...
Does it make sense to measure the diameter of the earth with a micrometer?

If you just said "The earth is big", I'll accept that.

If you said that the earth is 8,000 miles in diameter, I accept that.

But if you say the earth is 8241 miles in diameter, I'll say "No, its about 7926 miles at the equator and 7901 at the poles.

Since it's generated such a response, I created plot of the error between the two. The three dimensional plot attached below shows a MAXIMUM error of around 50 UPTD at the most extreme portion of the plot (i.e. a 50 UPTD error when your total exposure is around 1,000 UPTD). Oh, the error is in your favor too - it leans towards the conservative because you get more UPTD with the higher power. I would be worried about other things in that zone

Again, I didn't expect such an outstanding thread to evolve. The information was absolutely wonderful. Thanks again Doc's!!
