In fairness, I very much doubt that deadliest warrior is what SiuiS had in mind. Probably just used that title because it was the first one to come to mind.
More likely he was thinking of fight science, or one of those other nat' geo or discovery network shows.
There's exactly zero travel for the hosts of Deadliest Warrior.
You do have a point though. Entertaining as it is, Deadliest Warrior is -not- good science on a number of levels. From using base-line human averages for calculations in reaction speed and general movement to "experts" that clearly know everything about their weapons except how to properly wield them (with a few exceptions), they've got more than a few holes in their number crunching.
