Oh, the throw score was plenty clear! I think my comment was not very clear.
As I was finishing each level, I was in that pick-off-one-or-two-at-a-time mode, and I always thought "Was there a more efficient way to do this that a better player would do? Or did I do well and this is just how levels tend to end?" Maybe a target score or something like that would have let me know if I sucked or not. :) But probably I shouldn't even have been concerned with that.
