Two scenarios:

1. You know your stuff, and get a lot of the predictions right, including most of the more obvious ones.

2. You don't know anything and get most of them wrong, but you got lucky and picked a couple obscure ones right.

BoB's system seems to skew in favor of the latter. I think we would all agree that #1 takes more actual knowledge, whereas even a shinra like Miriel could accomplish #2.

Me? I suck at both.
