What did your lab checks expect?
Colleagues of mine on the College of Tsukuba in Japan took the International Cup ball, put slightly hollow in it, caught it on a rod, connected drive sensors after which set it up in a wind tunnel to procure a wide variety of aerodynamic information. They despatched that information to me to take a look at what the trajectory modeling for the ball urged about how it will carry out compared to its predecessors.
