taras22,
I am not sure what affidavit she was talking about, but it seems that it makes two of us. When it comes to math, there are lots of equations and calculations that could be involved, should one wanted to dig deeper into pressures and physiology, but that does become too technical and I never considered mentioning it. It helps understanding, but it gets complicated, too. Definitely does not end up in "plain English".
As I said, that gobbledygook was, indeed, simplified to extremes and in as plain of English as it could ever get. Now, when I think about it, maybe it was too simple for her usual approach.
