Interesting query, Nick, but I am finding that it is always interesting (so far) to (1) ask the AI to provide comments and footnotes with hyperlinks of why it did what it did and #2 run the same query multiple times in the same platform over set time phases and the same thing in multiple platforms. Then compare an contrast. Tom
