Your calculator is broken. .11 is exactly what it says it is. 0.11% of your blood volume is alcohol. If you make it to 11% BAC, you were dead about 8% earlier and the IV was left running.
Yea, my bad, you are correct of course. I was thinking in terms of this. 1*.5 = .5 or in other words half of one, or 50% of 1. But on reflection, 11% BAC is rather a silly notion. He ll, 1% BAC is silly. I was looking at it as a multiplier as opposed to what it actually is, which is a literal %.
