Comparing Results Between Shielders

Another note: If shielding is integrated into another robot, the best system isn't necessarily the one that would produce the best bullet-shielding-only score, but rather the one that, against it's opponents, either works really well or fails miserably. It's problematic if it produces a lot of ~90 scores, as there is no good way to know if this is better than your normal drive and gun.

Why not just compare the version with shielding to the version without shielding?

Different bots might gain different amounts from shielding based on what they got against susceptible bots in the first place. Since it can be tough to integrate a different person's shielding into your bot, this way we can compare shielding effectiveness without doing a ton of integration work.
