Obsession is an appropriate approach to an issue like this, though. I 
call it like it is, but I don't mean to judge.

That touches on two other valuable attributes of a documented 
methodology. The ability to repeat the test is the backbone of science 
and its applied forms such as engineering. The ability to design 
parameter-insensitive methodological controls is another; and this 
sounds like what you might be doing - checking for a vulnerability of 
Wilhelm's methodology using a technique in which all variables do not 
necessarily need to be solved in order to learn new information.

None of this is possible when tests do not include careful thought about 
methodology or are unpublished in their technical details, alas.

Yes, for the moment I'm feeling good about holding on to my 2200. :-)
