TAR19 got off on the wrong foot with me, because I felt that they completely mismanaged how to deal with the Hazard penalty and Leg 1 in general. "Oh here, we're gonna give you a penalty that could get you eliminated. But surprise, it's a non-elimination leg!" If I was a TAR producer, here's how I would've handled the first few legs of TAR19:
Leg 1: Hazard penalty for the last team to finish the Starting Line task. Last team to arrive at the Pit Stop is eliminated. (The whole point of the Hazard was to make a team have to fight even harder to stave off elimination. Having a Leg 1 NEL completely ruined that.)
Leg 2: NEL
Leg 3: Double Elimination (The Roadblock at Borobodur was confusing enough to cause teams to be eliminated.)
