I am learning a lot about cardiovascular physiology from this thread, so in that sense I am happy to see it going. However, I think we're getting way into "Wonderland" if we think that we can make any predictions about DCI from it. The basic problem is that we just don't understand as much about "fizzyology" as we do about physiology. The only prediction we can make about DCI is that it will be a LONG time before we understand it well enough to make any predicitons about DCI. I think a more fruitful approach is to go out in the real world and see what people are actually doing, and what sorts of things get people bent less often than other sorts of things. If you look at commercial diving fishermen in th tropical Pacific, you'll see that they are doing profiles that will keep you awake at night in a cold sweat. However, when you compare their bottom time to decompression time ratio with their rate of DCI, you'll realize that they know something about decompression that we "educated" types are missing altogether. The advantage they have is that they know absolutely nothing about decompression tables (and thus have no blinders on). All they know is what has worked and what has not worked in the course of tens of thousands of dives.
