The judges are re-tallying the score:

The things you are counting as failed predictions of the BBT are not predictions at all, they are aspects of the puzzle that the BBT does not explain. Thus they are to be viewed as incompletenesses of the theory, not errors in the theory. You can count them as flaws or problems, as any incompleteness would be, but that's more like having an olympic ice skater who does not include certain difficult jumps in her program, as opposed to jumps that she tried and ended up on her bumpty. When scientific theories fall on their bumpty, they are replaced. When they are incomplete, you just practice those difficult jumps a bit harder until you are ready to put them into your program and go for the gold.

In your baseball analogy, I'd put the BBT in the role of the pitching team, not the batters. The goal is to win the game, not pitch a perfect game. So when you are overmatched by the other team's heavy hitters, you intentionally walk them, and go after the ones you know you can get out. That's what BBT does-- it puts in a few intentional walks that after we develop a better changeup we can go after, but for now we'll just strike out the hitters we have in our back pocket.

Now, this is not an ideal state of affairs, but be patient. The changeup is coming. Or maybe we'll have to bring in a relief pitcher, who knows, but frankly there's nobody warming up in the bullpen at the moment. To sum it all up, I'll borrow from Winston Churchill: the BBT is the worst of all cosmology theories, except for all the rest.

Yes, that is right. Lots of luck, we have your Nobel prize waiting if you pull it off.
