I have noticed that the size of the balls has not been very consistent. Between competitions the powerball changed in size by at least 4 inches which made it nearly impossible to compress. I would like to know if the size at the championships will be closer to the size at the Northern competition or the Berkley one.
Keep in mind, all ball dimensions have a +/- size, as listed in the rules. 4 inches would seem like a lot of variation, though. It probably wasn’t that much, but if it was, that needs to be fixed.
The diameter at Berkley was almost exactly 24". The diameter at Holly was around 23.5". I did not measure the diameter at Pontiac Northern, but I’m sure it was not 20" or 28". All you can assume is that the ball will be somewhere between 23" and 25" and we’ll try to get it close to 24".
