It's a balance between cost and sensitivity, and remember that 1 discovery would prove the experiment a "success". I think the way it was planned and executed was great. Also, I think the proof that gravitational waves is far more exciting than comparing gravity wave signatures among a sample of celestial collisions.

This is sort of like saying that "proving that stars emit light" is more exciting than using better and better telescopes to compare electromagnetic wave signatures of different light emitting celestial objects.

We will likely learn a great many things over the coming decades with this new way of looking at the universe, many of which we couldn't have even guessed we would learn!
