What is the purpose of a bungeed bladder

[rfwoodvt]

Just beginning my Explorations into BPW setups. I seen reference to bungee cords on bladders and haven't quite figured out what their specific purposes.

Any enlightenment would be appreciated.

I alway thought a bungeed bladder helped one sleep through the night, as they get older.

There’s also the issue of an entanglement hazard with bungees.

One of the many myths in my opinion. If rigged correctly your cords are below the surface of the wing.
