So: I used your thingy as soon as I saw the TC announcement, and while I believe you when you say that there's substantial modeling happening behind the scenes, I didn't perceive any of that. My end-user experience with your offering was of a very, very usable... financial calculator.

One thing that might have sold me on what you're doing behind-the-scenes: if there was a "dumb calculator" result you could have compared your numbers to in the results screen.

(Apologies if I missed you doing exactly that).
