Yes, there is some variablility there - not just between models of golf ball but also with the same balls if some rubber or dirty collects on their surface. It is also not always the same balls from year to year, it is whatever the LOC (local organizing committee) can get. I remember using these before, but I am not sure if it was RoboCup German Open or the international tournament. I am pretty sure we didn’t use that exact model in Bangkok 2022.
In short: Unfortunately you cannot rely on the ball properties too well, if you already have different ones to test try to come up with a flexible solution, you will probably need it.
