Yes there is some room for interpretation on what “out of round” means. Use your best judgment.
For standard of measurement (if someone wants a standard): multiple attempts at rolling the ball across a flat surface over several feet (table or carpeted field) resulted in the ball not acting like a sphere (deflecting, wobbling, etc.)
