Your right of course.

There are a couple reasons not to fully inflate a suit. The 4 or 5 psi difference between 14.7 and inflated is dangerous if you loose your helmet or glove. It could injure your lungs or kill you.* Also they probably don't want the competition knowing what exactly is under the outer garment. BTW, there is competition as with a few tens of thousand of dollars for each suit some feel it is worth the R&D effort!

* At one point I thought this wrong because I've dived to 11 feet and return rapidly with no lung bursting. But this is different from say inhaling at 11 feet underwater and then rapidly reaching the surface. Which is what a rapid decompression of from a 19.7 psi pressurized suit to 14.7 psi would be like. Of course 0.5 or 1 psi is safe for most people.
