It seems to me that a common thread that pops up in the numerous "how much lift should I have" questions is that the exposure suit is always a relative unknown. How many new divers have actually measured how much weight it takes to sink their suit? I've never done it myself, I eventually backed into the right value by adjusting my weighting until I was neutral at my safety stop.
I've also never purchased a wetsuit before, so I'm totally assuming this is the case, but why don't manufacturers provide the approximate buoyancy of the suit? It doesn't really matter if it's in fresh or salt water, or if there's a range to account for manufacturing and neoprene batch variations, or a warning about how the number may change over time as the suit gets older. But for each size of suit, it seems like it would be very helpful to know how much weight it takes to sink it. At least it would provide a solid ballpark for divers to be able to work out their weighting and lift requirements. And it's not exactly difficult for a manufacturer to do.
Are there any downsides to to providing this information?
