I do not doubt the accuracy of Bio's data or his reponse. I was simply trying to relate that to OTHER web info that I have seen on many other sites. It just SEEMS like an awful lot of water, is all.
I am much too stupid to do the math and understand basic physics, and is why I asked for assistance in the first place.
I am trying to gain more knowledge. I have no interest in defending incorrect data sources.
Bio, you should know me better than that by now.....
Thanks again to all.
