Actually we did had measured the discs but then one of us checked the manual and told us they changed the size of the discs so that they were larger.
We made our shooter adjustable for this difference because the discs we received from the KoP were of the small size and we needed to practice.
All of those minor changes are always in the manual I suggest you to check it regularly in case they make a chenge. I know it's hard to read it all again but just check the important things such as sizes or the fouls.
