In my opinion there should be save state rule for Bungee Race. Walking back to the bungee spot is torture for me. I think teleporting back to it or jetpacking is quality of life. There should be a rule about this. I really don't enjoy playing bungee race, just because you need to walk the same paths many, many times during many turns, and it's definitely not fun to play this way.
Teleport back to the checkpoint you were should be a mandatory rule for Bungee Race. Teleport would need SDET. Jet Pack doesn't need SDET. Teleport is easier to go back, though. I prefer tele than jet.
About LDET for bungee, I think it will be like playing boom Race in single shot mode if no LDET, only rare, lucky or few exceptions would be able to progress without loosing the turn. Not sure about it, but definitely it is a skill to avoid the worm loose control.
