Dave,
Knowing the weight of the payload, they will fill it with enough gas to become neutrally buoyant at the target altitude.
If altitude is the goal, enough gas will be filled to take it to an altitude that will exceed the Burt diameter.

I have seen posts from time to time on the BB about balloons with amateur radio payloads on them.
I've got a question regarding the missions that carry payloads around the world. What stops the balloons from going up until they explode do to the high altitude. How are the packages kept from doing this to achieve such long distance flights?
