Anyone else noticed this? We are wondering if it has to do with our altitude, (almost 5000 ft) and how competing at lower altitude could affect our shooter if the size changes this much.

The balls aren't sealed, or at least ours is not. It has one small (0.1" -ish) orifice in the outer covering, so I would not expect any difference in diameter due to changes in barometric pressure.
The ball that came in our KOP measures 9.7" in diameter at 300 feet above sea level and weighs 290g.
