Yeah, I always seemed to zig when you wanted me to zag.
Calculus/Economy was something I think I didn't think about carefully enough. I was just thinking of applications of calculus and it seemed like the obvious one. I also thought it might have been Difficulty (because calculus is hard) that would have been fine it turns out. I should have thought about how you might have picked something more obvious if you'd been trying to connect it to Economy.
Pilot I thought you and I were both super clever for coming up with the pilot light connection. I thought it had to be the right answer, but oops.
Mode, the Manner guess was in connection to "Mode & Manners", a common if old-fashioned saying.
I'm glad you always went aggressively though and tried to get at least two at a time. Giving two away though made the game really close and let them play a lot safer. Bad luck that I constantly narrowed it down to two things and then picked the one that turned out to be blue. But when I missed one it gave me the chance to guess at the one I missed later in the game.
