Re: Consistent shooter

Ironicdeadbird is one of the mentors on my team, and we're talking about the same ball. A little more background:

Prior to Utah, we practiced with a ball that we deemed properly inflated. In Utah, the balls were slightly more inflated than we assumed they would be, and they became tighter as the event went on, so they seemed "overinflated" to me. Since returning, we've inflated our ball more to simulate field conditions. Yesterday we played with two balls that were not ours: one was very slightly under what we had been using prior to Utah, the other was the aforementioned yoga ball.

We shot from specific points on the field yesterday that we had previously tested. The distances were similar for the ball with "normal" inflation and very short with the other ball. Consistency is very hard to measure with our design, however, as ball shape, location in the shooter, and battery charge all effect it as well.
