Actually it's very correct. One ounce on either side of a 15 lb ball affecting reaction? Let's break this down. 16 ounces in a pound. 15 lbs. That's a 240 ounce bowling ball. Broken down into two separate halves, 120 ounces. Moving one ounce from one side to the other is less than a 1% difference. Even logically it makes no sense. Now naturally the conversion percentage isn't the same for floormats in an SUV, but theoretically it has the same effect. Nothing.
