1) Sure. Whatever the number needs to be to make it a reward.
2) And I agree, which is why I said a walk, or a run, because let's face it...if the pitchers are doing their jobs, the batters *should* hypothetically be getting themselves out 70+% of the time.
But if you're giving up a run, without a walk, without getting an out...well...you're just having a textbook poor inning, and shouldn't be rewarded for that, either.
