Note on the travel time information above:
The histograms and the above two charts (near) exclude duplicate names and include changed names. Excluding duplicate names is necessary since travel time information related to them is unreliable and nonsensical- for instance, passing exam P three years before receiving a designation.

Including changed names has an impact on the relative number of people who passed other exams vs. the given exam. Their inclusion will lower this ratio since changed names will not properly link between previous/future exam passes. However, including changed names will not affect the average travel times, since travel times of changed names are not necessarily different than those of unchanged names.

For exam ST on all sittings, there were 47 duplicate names, 489 changed names, and 9 duplicate and changed names.
