It's a very different game in person. I can't emphasize this enough. My get rate is ridiculously high at home. In person, the game moves a lot faster, and it's harder to recall things you know with the lights and added pressure. These teachers are not dumber than the average contestant; I certainly am not. However, if you haven't played live it's very easy to sit at home and think contestants just don't know things. It's more complicated than that.
FTR, I knew Miles Standish, and I knew most of the TS's. None of that knowledge helped me when I played in person. Again, it's different in a way I can't really explain.
