Further extensions of the method might involve outsourcing the visual processing to external observers, such as those provided by a service like Amazon Mechanical Turk (mTurk) (Buja et al. 2009: 4381). Amazon mTurk is particularly useful for testing at p-values lower than 0.05, since there are limits to the number of graphs a person can simultaneously compare, and space (and boredom) limitations preclude including pages of plots in journals.
TTT plots for ascent rates would necessarily require different calculations than those proposed in this Article, because climbers can have multiple ascents. Unlike death, success does not censor further observation of a climber.
