Re: Ball dimensional variability

We measured our ball shortly after inflating to what we thought was a "normal" inflation, and got 24".
It's since been left overinflated for about a week, and after filling it until the zipper just closes, we measured 25.75". Unlike you guys in the States, though, we've had a week of 90 degree days, so possibly that's a factor.
