I have seen several posts about ball weight. I know this matters, but we need to know the pressure inside the bladder so we can collect data on how much the ball will compress. The data in 2014 BALL Inflation and Maintenance Guide is not very exacting.
6. Inflate the BALL so that the zipper appears as in the “Properly Inflated” figure below. The BALL
on the left is under-inflated, while the BALL on the right is over-inflated. When properly inflated,
the zipper will be able to be pulled and closed, not too hard, not too easy.
